This Week’s Jewellery Pick

Posted on by

This week I saw a lovely collection of antique jewels, dating from the mid-19th century. Mid-19th century felt ‘relatively’ close until I realised it was getting closer to being 200 years old rather than 100… If you’re like me, the 80s was still only 20 years ago! Enough revelation on how old I am and back to this beautiful collection.

The one piece which caught my eye was an onyx mourning brooch dated 1854.

The oval onyx plaque, measuring 4cm x 4.5cm, has an overlaid border of acanthus leaf gold detail, the central glazed compartment with a lock of hair within a surround of 31 seed pearls, in closed-back setting. The reverse was engraved with ‘In Memory of Henry Thomas, Sept 14th 1854, Oct 54 years & 11 Months’.

Though its value might be relatively low, around £500 for Insurance purposes and £200 for open market value, one can immediately sense the priceless sentimental value this piece had.

When Prince Albert died on 14th December 1861 of typhoid fever, Queen Victoria entered a state of mourning and wore black for the remainder of her life.

It was then that onyx became fashionable. The court was quick to follow the new strict “dress code”. With wars and epidemics, death was everywhere. The demand for hair for mourning jewellery was such that it is said an extra 50 tonnes of human hair a year was imported to England to meet the demand.

Though a very personal jewel, the demand for mourning jewellery is constant. The below items, comprising of two mid-19th century gold and enamel mourning brooches and an 1830s gold locket, sold at Bonhams for £1,000 (including premium).

Mourning jewels are both sad and a beautiful statement of the love someone has for a departed. Whether antique or new, it is a celebration of the life that once was.

Stay tuned for next week’s jewellery pick…

Jewellery Valuation

Designer Jewellery Trends – An Upward Curve?

Posted on by

There is no doubt that values in the designer jewellery field have seen uplifts in the past few years. A unique combination of the Post Pandemic luxury goods ‘boom’, an exponential rise in social media influences on buying patterns, wider inflation and bullion prices have all contributed to an incredibly buoyant and enduring atmosphere.

Similarly to the trends seen over the last couple of years in the watch market, particular designer brands saw a huge increase in popularity, visibility, and subsequent demand on the secondary market, with only a slight respite towards the end of 2023 (Reuters).

Coupled with retail prices ever increasing, the value of these ‘hot’ designer items have been pushed up on the secondary market. Value factors include condition, whether the piece has its box, and the perceived popularity or rarity of any gemstones used in the design.

Cartier

Whilst Cartier’s growth in the retail sphere appeared to be easing towards the end of last year, share prices and figures released in January 2024 display a definite upward curve driven by demand in Asia. This healthy overall trajectory has filtered down to the secondary market, with Cartier items at auction demonstrating a strong sales rate and frequently exceeding estimate.

‘Love’

The last retail price increase for Cartier was implemented in early 2023, with prices rising from anywhere between 3% to over 10%. The most sought-after and iconic collections naturally increased the most, with Pursebop estimating the retail price of an 18ct white gold Love Bracelet set with four diamonds increasing 7% to £12,200.

The Cartier ‘Love’ bangle is one of the most popular items of jewellery ever designed. Created by Aldo Cipullo in 1969 and were referred to as a ‘modern love handcuff,’ only removable with the help of a mini screwdriver.

Worth noting that some designs, including Aldo Cipullo original LOVE jewels from the 1960s onwards will always command a premium for their place in the brand’s design history. Another 1960s design by Cipullo to continue to grow in retail price is the Juste Un Clou, with a ‘small’ diamond set bangle selling for £4,850, and a diamond-set choker necklace now retailing at £105,000.

Cartier Trinity

This year, to celebrate 100 years of the Trinity Collection, Cartier has released two new designs, a re-edition of the XL bracelet and an XL version of the iconic ring. Maintaining the timeless appeal and enduring relevance of this beautiful collection has seen values continue to rise over decades, resulting in a classic collection that is still coveted a century after its creation.

Van Cleef & Arpels

Another brand under the Richemont umbrella is Van Cleef & Arpels. Van Cleef & Arpels was established in 1895 following the marriage of Estelle Arpels, daughter of a dealer in precious stones, and Alfred Van Cleef, son of a lapidary. Creating masterpieces such as the ‘invisible setting,’ the minaudière, and the zip necklace, this iconic jewellery house is perhaps best known in present times for the ‘Alhambra’ collection. Indeed, according to statistics by retailer Watch Pilot, in 2023, the Van Cleef Alhambra bracelet was the most Google searched item of jewellery by category.

VCA Alhambra

Designed in 1968 by Jacques Arpels to be symbolic for luck, the Alhambra Collection is designed around a series of quatrefoil ‘four leaf clover’ panels. Varying in designs with quantity, size, and gem material, these beautifully set clover shapes are truly emblematic of the brand. Worn by royalty and celebrities to include the likes of Princess Grace of Monaco, Elizabeth Taylor, Kate Middleton and many more, the Alhambra collection possesses a truly timeless appeal.

Since 2022, the retail price for an 18ct gold Alhambra bracelet with five mother of pearl motifs has increased by 5.3% to £3,950.

At auction, the Van Cleef Alhambra pieces that well exceeded estimates were limited edition runs and unique pieces that were impossible to procure from the retail market.

One such example was a striking collar necklace, formed from openwork Alhambra links in 18ct yellow gold, selling at Bonhams in 2022 for £50,000 against a £12,000-15,000 estimate.

Boodles

Boodle & Dunthorne was established in Liverpool in 1795, gaining a reputation as one of Britain’s finest jewellers. Rebranding to ‘Boodles’ in 2004, this coveted brand has designed several sought-after jewellery collections that continue to enjoy increases in value as the years go by. Collections such as the Velocity, Blossom, and Raindance are all designed and handcrafted in-house from Boodles’ workshops in the heart of London.

Raindance

Designed in 2000 and inspired by a trip to the Chelsea Flower Show in which Head of Design Rebecca Hawkins admired the way light played on raindrops, the Raindance Collection is seen as one of the brand’s most iconic collections. Indeed, the Victoria & Albert Museum has a Raindance ring on display as part of their ‘Best of British Design’ permanent exhibition.

Featuring a series of collet set diamonds in varying sizes and angles, these beautiful jewels are retailing from £3,400 for a single band set with three circular rubies or sapphires and a pair of brilliant cut diamonds. At the top end of the spectrum is the Raindance ‘Chelsea’ bracelet, set with over 15 carats of colourless and fancy pink diamonds at £134,400.

Celebrating its 20th anniversary in 2020, Boodles released a limited-edition ring, set in platinum and 18ct rose gold with colourless and Argyle pink diamonds. Varying in carat weights, these limited edition pieces will continue to grow in value and hold their own at auction. In 2023, one such example with approximately 2.80cts of diamonds sold at Tennants Auctioneers for £19,000. Meanwhile, a version of the design on Boodles website set with 4.25cts is available for purchase at £84,000.

To conclude, exquisitely constructed and expertly finished jewellery will always possess a value, and continue to rise according to demand, popularity and inflation over time.

Although trends and fashionable collections will alter and vary over the years, items from the premier jewellery houses, in good condition and with original boxes will retain a demand from collectors, jewellery lovers and indeed those new to the market. Pieces that possess an unusual or rare aspect, such as an early piece from the collection, limited edition runs, and unexpected gemstones can expect to exponentially increase in value over time.

With the clear discrepancy between open market value and retail replacement value, it is essential that clients are equipped with adequate cover for their items.

Unveiling the Brilliance Lab-Grown Diamonds

Posted on by

When is a diamond not a diamond?

What do you call diamonds that are not formed underground but grown in a controlled environment that mimics the conditions under which natural diamonds develop? So, are they synthetic, lab-grown or factory grown or simply ‘diamonds’?

First of all, lets look at how you ‘grow’ those divine diamonds.

There are two popular ways to grow a diamond. Both involve starting with the ‘seed’ of another diamond. The first lab diamond was made in the 1960’s and the industry has changed massively in size and complexity in the intervening 65 years.

The growing of LGD’s is a little like the VHS and Betamax fight in the 1980’s. The first option is using a High Pressure High Temperature (HPHT) system, where the seed is then placed amidst some pure graphite carbon and exposed to temperatures of about 1,500C and pressurised to approximately 1.5 million pounds per square inch in a chamber. The alternative model to make diamonds is called Chemical Vapor Deposition (CVD). This was slower out of the starting blocks but the quality and size of diamonds produced using this method is arguably superior to HPHT.

This system involves putting the seed in a sealed chamber filled with carbon-rich gas and heating to around 800C. Under these conditions the gases begin to “stick” to the seed, growing a diamond carbon atom by atom.

No one knows quite yet who will win the fight like VHS did back in the day. Vast research development and investment is being put into both practises with neither side prepared to admit defeat yet.

LGD’s represent nature at its most perfect, at a fraction of the price of a natural diamond.

Retail

  • 3ct G VS1 round brilliant cut LGD in 2021 – £16,500
  • 3ct G VS1 round brilliant cut LGD in 2023 – £7,500
  • 3ct G VS1 round brilliant cut certificated natural in 2021 – £55,000
  • 3ct G VS1 round brilliant cut certificated natural in 2023 – £70,000

Some of the questions we are asked are ‘Are they real diamonds?’ and ‘Can you tell them apart from a natural diamond?’

The answer is yes to the first question. They test as a diamond (2.412 on a refractometer) visually and chemically identical to a natural diamond.

However, they can be told apart by those in the know.

Using LWUV and SWUV (long wave ultraviolet and short wave UV) the florescence of a factory made stone is an absolute giveaway. They often have a strong turquoise or purple colour that you never find in the natural world. The growth structure can also give away a man-made diamond because they were grown so quickly, the atomic structure does not have the same chance to settle into a classic framework.

The pricing of diamonds, whether natural or labgrown, depends on various factors such as carat weight, cut, colour, and clarity. While lab-grown diamonds are generally more affordable than their natural counterparts, the price difference is becoming more pronounced as technology advances and demand grows.

Natural diamonds are esteemed for their rarity, formed over millions of years deep within the Earth. Lab-grown diamonds, despite sharing the same physical and chemical properties, are sometimes perceived as less valuable due to their manufactured origin. Costs over the last two years has dropped in value of these stones while natural diamonds are keeping their value.

The latest findings propose that there is very little resale value for a LGD. Many auction houses will not take them and many of the large fine jewellery houses will not sell them including De Beers who set up their own LGD factory and company for their ‘Lightbox’ ranges. They stopped making engagement rings in 2022.

The marked retail price difference gives rise to the challenge in ensuring transparency and proper disclosure to the consumer. Some critics argue that buyers may not always be adequately informed about whether the diamond they are purchasing is natural or lab-grown.

Due to the price differential this could be a devastating find?

Did you know; if a diamond is marketed or sold or valued as a ‘diamond’, without a pre-fix such as lab-grown, synthetic etc, then it is assumed to be an earth grown natural diamond? All lab-grown diamonds of any shape or size must have a pre-fix to aid a consumer’s educated decision process.

During a recent valuation, a diamond ring was presented from a charming young man, who had purchased it to propose to his girlfriend. However, during our appraisal, Annabell had to give him the devastating news that it was not a natural diamond. He had purchased the stone for £38,000 when infact,the price should have been around £9,000– did the jewellers know it was lab grown?

This type of miss-selling has caused the potential for market confusion. Consumers might face challenges distinguishing between natural and lab-grown diamonds, impacting the perceived value of their purchases. So, it is important to buy your jewellery from a recognised jewellery company.

Having reviewed some of the challenges for LGDs verses natural diamonds, they are still hugely popular. In August 2023, LGD amounted to 50% of all diamonds purchased in America. Pandora, who are one of the world’s largest jewellery companies, uses LGD for many of their designs. Gems TV and ‘fashion jewellery’ brands are developing price sensitive ranges for LGDs and because of the size of the market and the lower margins being made, the producers are concentrating on melee size cut goods for watches and ‘halo’ rings and larger (2ct plus) ultra high quality diamonds, such as E & F colour VVS clarity.

So, are Lab-Grown Diamonds here to stay… the rise of lab-grown diamonds is indicative of a broader trend toward sustainable and ethical practices in the jewellery industry. While traditional diamonds maintain their allure and value, lab-grown diamonds are carving a niche for themselves, driven by consumer demand for more price sensitive choices. As technology continues to advance and consumers prioritise ethical considerations, lab-grown diamonds are likely to remain a significant player in the market. However, the coexistence of natural and lab-grown diamonds is expected, with each catering to different preferences and values. The issues associated with lab-grown diamonds against natural stones are multifaceted, touching upon perceived value, ethical considerations, disclosure, and market dynamics.

Will natural diamond values increase due to scarcity? Will women prefer to have a natural diamond on their finger rather than a lab-grown diamond or will price decide?

We wait and watch!

Antique Jewellery

Antique Jewellery

Posted on by

Antique, heirloom second-hand jewellery is a finite commodity, sometimes incorporating unrepeatable craftsmanship and irreplaceable gemstones.

Some of my favourite jewels are antique pieces. The reason is simple: exceptional quality and craftsmanship. One could argue that with today’s tools and technology, jewels are just as well made, if not better. But there is a difference, the exquisite craftsmanship from a hundred, or two hundred years ago was so exceptional that these “artists” accomplished unique pieces, without our modern tools and are still admired to this day.

Cartier is often the go to example when discussing unique skills, then and now. The above Art Déco sautoir by Cartier, was sold at Christie’s in May 2012. With an estimate of CHF74,000-110,000 (approx. £60,000-85,000), it sold for CHF 507,000 (approx. £400,000), excluding premium. The hammer price reflects a combination of excellent work but also unique gems. The quality of the emeralds would have been chosen to be the most vivid green, eye-clean or with very few inclusions. And the pearls, would have had to be selected minutely to match in size, colour, overtone and quality. Any blemish to the nacre, and the pearl would have been discarded.

This necklace would have required hundreds of hours from skilled jewellers and tradesmen.

Another example of the skilled work is this below Belle Epoque pendant watch by Cartier. The pink is enamel and the technique is called guilloché enamel. It resembles waves and the know-how to achieve this is unparalleled. It was sold for CHF7,500 (approx. £6,700) excluding premium at Sotheby’s.

Though the technique requires exceptional skill, the piece’s relatively “low” value for an antique Cartier jewel, can be explained by the lack of gems. Unlike the sautoir, only a few rose-cut diamonds were used in this piece. As complex and unique as this piece is, the demand for such an item is less than, for example, the below rock crystal and diamond Art Deco bracelet by Cartier, and therefore commands a lower price.

The rock crystal and diamond bracelet sold at Sotheby’s for USD237,500. The seven larger old European-cut diamonds, weighing approximately 11.60 carats, are approximately H-I colour and SI-I clarity. The smaller old European, old mine and rose-cut diamonds, weighing approximately 6.80 carats, are approximately G-J colour and VS-I clarity. This piece, just as with the sautoir, is a perfect combination of choosing good quality gems, and working with a semiprecious gem, rock crystal, in such a manner, that probably only a handful of people could ever deal with. The bracelet was sold with a note from the jewellery department stating that it is “exceptionally flexible and supple”. An incredible achievement.

Side stepping away from the worldrenowned jeweller, is Bvlgari. In the 60s, Bvlgari created an entire collection based on antique and irreplaceable coins, the Monete collection. Launched in the 60s, it is one of their most celebrated and successful collections, worn by private individuals and also Hollywood glam, such as Anne Hathaway, below, wearing Monete High Jewellery by Bvlgari.

Their collection includes coins from centuries BC, and never-used replicas. This meant there was limited supply and sourcing took a long time when they initially launched the collection. As popularity grew stronger, sourcing became easier and quicker. Though readily available, these jewels still retail for several thousands, and tens of thousands of pounds.

Irreplaceable gems and antique jewels make up some of the most precious collections, whether on display in a museum or on sale at auction. Exceptional prices and auction sale results will always take the world by surprise but can we actually put a price on a unique antique items of jewellery? Sentimentality will always play a role when inheriting jewellery, and who could put a price on those feelings.

Discovering Sotheby’s Auction

Vienna 1900: An Imperial and Royal collection

On the 6th and 7th November, Sotheby’s Geneva will be auctioning some of the finest antique jewellery from the 1900s, described as Belle Epoque jewellery. This collection is unique in that it groups prestigious gems, such as emeralds, sapphires, rubies, and natural pearls, but also in that these pieces have been kept intact all this time. It is becoming increasingly rare to find pieces from over a century ago. Jewels are very often broken up and stripped of their gems and metal. It is, in my opinion, a great shame, as the craftmanship of that period was stunning and very refined.

Belle époque jewels are characterised by bows, ribbons, swags and flowers, and items mounted en tremblant. Meaning to tremble, en tremblant diamond-set flowerheads (for the most part) are attached to a thin metal wire spring which trembles with movement. This gives the illusion of life and allows light to reverberate into the diamonds, bouncing off and reflecting “fire”, all the colours of the rainbows. It is often found on tiaras, brooches or devant de corsage such as lot 1089 of the sale.

Gifted by Philipp, Duke of Württemberg (1838-1917) as a wedding gift to his bride Archduchess Marie Therese of Austria – Teschen, Duchess of Württemberg (1845 –1927 in 1865, it is composed of natural saltwater pearls and approximately 60 – 75 carats of diamonds. It comes with an estimate of CHF270,000 – 450,000 (approximately £245,000 – 410,000).

Selling with the same estimate is a natural pearl and diamond brooch, circa 1865.

It is set with a first button-shaped pearl, measuring approximately 14mm and suspends a larger drop, measuring approximately 19mm. They are highlighted by approximately ten carats of diamonds.

This piece and its estimate are an indication of exceptional provenance but also reinforce the importance of having certificates for unique gems. These two pearls have reports from the reputable laboratory SSEF in Switzerland. When looking to insure or sell, reports will be a key part of valuing an item correctly.

In the example of the above brooch, if the pearls were not natural, its value would be mainly in the diamonds. It is their natural origin that give it a hefty price tag.

What do we call natural pearl?

Natural, as opposed to cultured pearls, are created in the wild, without human intervention. Cultured pearls are grown in farms and commonly are bead nucleated. This means a nacre has been formed around a nucleus as way for the pearl of defending itself. The pearls are then collected anywhere from six months to 3 years depending on the type and environment in which they are grown.

To illustrate further the uniqueness of the pearl and diamond brooch sold by Sotheby’s (above), the retailer Hancocks, who deals with antique jewellery, currently sells a natural pearl and diamond brooch for £22,500 (below). The pearl measures approximately 11mm and there are close to five carats of diamonds.

There are a variety of jewellery for women of course in this sale but also for men. Beautiful emerald cufflinks for example are also for sale.

The above cufflinks are centrally colletset with rose-cut diamonds within a navette-shaped emerald terminal. They belonged to the Tsar of Bulgaria and have an estimate of CHF3,600 – 5,500 (approximately £3,200 – 5,000).

Cufflinks and medals were worn with uniforms for balls, together with neck badges such as the below.

This beautiful gem-set neck badge has an estimate of CHF36,000 – 55,000 (approximately £32,000 – 50,000) and is adorned with a Ceylon sapphire, accompanied by an SSEF report stating it has no indication of heat treatment.

In this instance again, a report is essential and its findings are reflected in the estimate. Heat treatment is often used in sapphires to deepen a stone’s colour and, although a common practise, can detract from a gem’s value. The key factors of quality of this sapphire, together with provenance and other gems in the piece makes it a stunning piece.

This collection embodies the late 19th century, early 20th century era of court, wars and balls with delicate attires and military uniforms. Waltzes and lavish court dinners with men and women draped with the most exceptional jewellery, reflected who they were in society, and if judging by the quality of these pieces, it is no surprise they could have been considered semi-Gods.

On a personal note, I wish great success for this sale in association with Duke Philipp of Württemberg, who I had the extreme pleasure of working with at Sotheby’s.

The Evolution and History of Diamond Cutting

Posted on by

Believed to be a gift from God, diamonds were first discovered in India in the 4th Century BC and were recognised for their hardness and strength. They were worn as adornments to ward off evil and provide protection in battle. Diamonds were also used as a medical aid; thought to cure illness and heal wounds when ingested. This was later dismissed, and it was thought that diamonds were highly poisonous; a rumour introduced to stop miners stealing diamonds by swallowing them.

Up until the 18th Century the only known source for diamonds was in India and their value was still considered much less than sapphires and rubies.

Alexander the Great opened a small trade between the East and the West in the mid-4th Century but it wasn’t until much later in the 14th and 15th century when diamonds entered Europe through Venice. They made their way north to Bruges, Antwerp and Amsterdam making these cities bustling diamond centres. It was at this point that European and Indian cutters begin to experiment with diamond cutting.

Point Cut Diamond

The earliest diamond cut is the point cut and was popular in the 15th Century. Cutters used diamond grit and olive oil to simply polish stones in their natural octahedral form. Olive oil was used due to its ability to tolerate the high temperatures caused by polishing.

Below is a diamond crystal in its natural octahedral form and a diamond ring set with multiple polished point cut diamonds.

Point cut diamonds are very rare as many of the original diamonds were re-fashioned as cutting techniques and styles changed. Here is an example of point cut diamond selling at auction for £11,000, well exceeding its pre-sale estimate of £1,800 – £2,400.

The Table Cut

In the mid-15th Century cutters designed the table cut diamond, they used the same polishing methods and simply removed the top point of the octahedral shape to produce a table.

This style of cutting possessed far better optical qualities than its predecessor, with greater brilliance and fire. It also displayed, when viewed from above, the impression of a table within a table, which fitted perfectly with Renaissance Europe’s love of classical proportions. The table cut became far more desirable than the point cut, which is why it is now rare to see examples of the point cut diamond as most were re-fashioned into the table cut.

Throughout the 16th and 17th century, variations of the table cut shape such as rectangles, triangles and tapered diamonds appeared.

Here are some more examples of diamonds with a table cut selling through auction.

The Rose Cut

The early 16th century saw the birth of the rose cut diamond. This made use of the flat rough instead of the octahedral crystal that we have seen so far. It proved the most efficient way to retain the weight of a flat crystal. The flat bottom and faceted domed top proved much more effective at displaying brilliance but not fire.

The Mazarin Cut

After developing and perfecting table and rose cuts, European cutters started to experiment with new cuts and styles. Cardinal Jules Mazarin requested that cutters in Europe designed a faceted diamond. The result was a cushion shaped diamond with 34 facets called the Mazarin cut, also known as the double cut.

The Old Single Cut

The mid-17th century saw the introduction of the single cuts. Like the point and table cut, the single cut resembled the shape of the octahedral rough. It also displayed more potential for brilliance than the table cut because it had more facets. This cut served as the basis for the modern brilliant cut and even today, the single cut is still used on smaller diamonds.

In the early 17th Century, the mines in India were running low on diamond source and European cutters needed more stones to continue experimenting with cuts. Luckily at this time, while miners were panning for gold in Minas Gerais, Brazil, a few odd crystals, and pebbles were found. Not knowing what they had discovered the miners used these stones to keep score during games of cards. It wasn’t until an official saw them that they realised that in fact it was a new diamond source.

The discovery of alluvial deposits in Brazil meant great things for the cutters in Europe. The diamonds rivalled those of India, and Brazil became the main source of diamonds for Europe.

At this time, Europe had a great desire to experiment and evolve the diamond cut, and there was an increasing interest in optical science. With the aid of advanced lighting and the modernisation of technologies, the developments of the first modern brilliant cuts could start to take place.

The Peruzzi Cut

The new rough from Brazil was used to create the first old mine cut also known as the Peruzzi Cut; this has the same number of facets as the round brilliant, but with a high pavilion it resembles a cushion shape. In 1750, a London jeweller called the new style of cut a passing fad and said the classic rose cut would outlast them all.

Today, antique cushion cut diamonds remain extremely popular and sell very well. Here are some examples – notice how almost all exceed their pre-sale estimates.

The round brilliant cut diamond

Years of experimentation with cutting led to the production of the modern brilliant. We can see examples of the modern brilliant cut being traced to the 1800’s. Henry Morse had been trying to achieve the optically efficient cutting design. It was however Marcel Tolkowsky in 1919 who published his PhD thesis called Diamond Design. This used mathematical calculations that considered how to display both brilliance and fire in a diamond. Tolkowsky understood that if a diamond was cut too shallow or too deep that the light entering the stone would leak out of the side; this discovery was achieved by systematically analysing the optics of a diamond. Although this was revolutionary for its time, there have been other claims on the perfectly proportioned diamond. In 1940, Eppler produced the European Cut and later in 1970 The IDC (International Diamond Council) also produced a set of ideal ranges.

Compared Results

These differing proportions are all aiming to show the viewer the perfect amount of brilliance and fire. Brilliance is the reflection of light from the back facets when viewed from the top of the stone. Fire is the splitting of white light into the spectral colours as the light passes through inclined facets.

Altering the angle of the crown will affect the balance of brilliance and fire.

Fancy Cuts

In more recent times we have seen variations of the round modern brilliant cut diamond. Cutters have applied the same perfected proportions displaying great amounts of fire and brilliance and applied them to the Pear and Marquise cuts. The Pear and Marquise cuts have been around for centuries but never before displayed the optimum optical properties. Furthermore, this led to the production of more fancy shapes in the brilliant cut; heart cut and princess cuts are now examples of this. Triangular diamonds cut in this way were even named the Trillion cut.

With many attributing factors that have been considered in the cutting of diamond throughout its evolution; from a polished octahedral crystal through to the brilliant cut diamond displaying fire and brilliance, I wonder what the next seven centuries will bring. Will our future generations look back and consider the brilliant cut diamond a primitive design compared to what this stone, advanced technologies and creative cutters achieve in the future?

 

What to wear for Wimbledon

Posted on by

For Ascot it’s all about hats, at Henley it’s blazers, but what to wear for Wimbledon…?

Let’s start with jewellery and what more fitting piece than a tennis bracelet. One of the most sought after easily worn pieces in any capsule jewellery collection and beyond, this now ubiquitous item came to prominence in 1987 when, during a match in the U.S. Open, Chris Evert ‘lost’ her diamond bracelet when the clasp broke. Play was suspended so that it could be retrieved, which it was.

She later said “When I competed, I wanted to wear something that gave me confidence and empowered me, both as a woman and an athlete. My tennis bracelet added a personal element to my style on the court and served as a daily reminder that I can do and be anything.” Who wouldn’t want some of that?

This style of line bracelet has been popular since the Art Deco period, but it was Chris Evert that brought it to such wide prominence and caused the change of name.

Tiffany Victoria diamond tennis bracelet which retails for £19,700

You’ll also be needing a stylish watch and there is a plethora of choices endorsed by tennis stars. Roger Federer became a brand ambassador for Rolex in 2006 with what was, at the time the largest single endorsement for any professional athlete. He was contracted to Rolex for 10 years for which he received $15,000,000. Others now in the Rolex stable are Dominic Thiem for the Daytona; Garbiñe Muguruza with the DateJust and Jo-Wilfred Tsonga with the Milgauss. If you want to dress the part but favour other brands, Nadal wears a Richard Mille and Serena Williams an Audemars Piguet diamond outrage.

Perhaps you will fancy something unique and eye catching to adorn your outfit, you might look at vintage novelty tennis related items. These two tennis racket brooches were sold at auction and the ruby and diamond brooch is Edwardian and set with ruby, pearls and rose diamonds.

Last year Ralph Lauren unveiled new uniforms for the court officials. The instantly recognisable polo shirt is now produced in wide navy blue and white stripes and they stated that they were combining the heritage of the brand with sustainable modern fabrics and modern silhouettes.

As for the outfit itself no-one does Wimbledon better than The Princess of Wales. As Patron of the All England Club and a keen tennis player herself, she often attends the championships and well as presenting the trophies.

In 2022 she chose polka dots by Alessandra Rich and a bright yellow dress by Roskanda. If you wish to emulate her style, similar dresses are available by these designers at about £1,400 each.

Whatever your style choice and however you enjoy watching Wimbledon, we hope you enjoy the championships and regardless of your outfit, the event is definitely best served up with Pimm’s; and strawberries and cream.

The Crown Jewels for the Coronation

Posted on by

On May 6th King Charles III will be crowned in Westminster Abbey. A tradition dating back nearly 1000 years since William the Conqueror who was crowned in 1066. Charles’s will be the 38th coronation in the Abbey, most, like Charles’s, having been conducted by the incumbent Archbishop of Canterbury.

We are expecting a simpler and more paired back coronation for King Charles, but this does not mean that it is going to be light on tradition and ceremony. This historic event will still be an occasion for spectacle and celebration.

It is a ceremony that has remained essentially the same for a thousand years and the Coronation Regalia are at the heart of proceedings, imbued as they are with cultural and spiritual significance. They represent the powers and responsibilities of the new King and the solemnity of the occasion.

The last time we saw some of the regalia of the coronation was on the late Queen’s coffin, which was adorned with the crown, orb and sceptre.

These three items will play an integral role at the heart of the coronation service, but they are not the only pieces that we will see on the day.

St Edward’s Crown is the crown historically used at the moment of coronation and worn by Her Majesty Queen Elizabeth at her coronation in 1953.

It was made for Charles II in 1661, as a replacement for the medieval crown which had been melted down in 1649 by Parliamentarians. Charles will wear this crown. The crown is 22 carat gold, so almost pure gold. It stands 30 cm tall and weighs an impressive 5lb. It contains tourmalines, white and yellow topaz, rubies, amethysts, sapphires, garnets, peridot, zircons, spinel and aquamarines. The three superstar gems in the crown are the Black Prince’s ruby, the Stuart sapphire and the Cullinan II diamond. No wonder Queen Elizabeth used to practise wearing it before the coronation, so its weight was not overwhelming on the day.

Camilla, the Queen Consort, will wear the Queen Mary’s Crown. This was removed from display at the Tower of London for modification work ahead of the coronation. It is the first time in recent history that an existing crown will be used for the coronation of a Consort. For previous coronations a new crown was commissioned. However, as a concession to the prevailing economic climate; sustainability and efficacy this crown, originally made by Garrards for the 1911 coronation, is being repurposed. Some minor changes and additions will be undertaken by the Crown Jeweller. These changes will pay particular tribute to the late Queen Elizabeth, as the Crown will be reset with the Cullinan III, IV and V diamonds. These diamonds were part of Queen Elizabeth II’s personal jewellery collection for many years and were often worn mounted in brooches.

At the heart of the ceremony itself are the sceptre, orb and the coronation anointing spoon. The Sovereign’s Sceptre and Cross symbolises the crown’s power and governance. It has been used at the coronation of every monarch since 1661. It was first used by King Henry VIII in 1509 for his own coronation. It is a golden rod, enamelled and set with multiple gemstones, the best known of which is the Cullinan I, or Star of Africa, a heart-shaped diamond weighing a colossal 530.2 carats.

In the photograph of Queen Elizabeth’s coronation you will see a second sceptre. This is the Sovereign’s sceptre with Dove. It is also known as the rod of Equity and Mercy and depicts an enamel dove wings outstretched alighting on the golden orb and cross. It represents the monarch’s spiritual role as head of the Church of England.

The most ancient piece of the coronation regalia is the coronation anointing spoon. The monarch is anointed with holy oil. The Chrism oil which will be used on May 6th has already been consecrated in Jerusalem. The oil itself comes from olives grown on the Mount of Olives and has been infused with sesame, rose, jasmine and other essential oils.

The spoon is silver gilt. Its existence was first recorded in 1349, but it may be even older. It is ornate with a central division and has been used to anoint monarchs for nearly seven hundred years. The central division may have been so that the archbishop might dip two fingers into the holy oil as he anoints the head, breast and hand of the new monarch.

It is traditional that the choir sings ‘Zadok the Priest’ during this sacred part of the ceremony; music originally composed by Handel for the coronation of King George II in 1727 and which has become an integral part of the proceedings.

The anointing is followed by dressing of the monarch in the spectacular robe of cloth of gold called the Supertunica and the long Imperial Mantle. The monarch is then presented with other items from the Coronation Regalia.

These include the gold spurs, the jewelled Sword of Offering and the Armills. The Armills are gold bracelets representing sincerity and wisdom. It is at this point that the monarch also receives the Sovereign’s Orb, as well as a ring and two sceptres.

The Orb is placed in the right hand of the monarch, during the investiture as the symbol of sovereignty. As a cross mounted on a globe, it represents the Christian world and the power of God. It is a reminder to the monarch that their authority is given by God. It is bisected with applied bands incorporating clusters of emeralds, rubies, sapphires and rose diamonds between bands of pearls. Having been handed to the King, it will be removed and placed on the altar before the moment of crowning.

The King will also be presented with the pair of golden spurs. These were first included amongst the regalia of the coronation in 1189 at the coronation of Richard the Lionheart. These represent his ‘knightly values and virtues’, such as protecting the poor, and defending the church. The current spurs are gold, made in 1661 for Charles1 and adapted in 1820 for George IV. In the past, the spurs were attached to the sovereign’s feet, but on May 6th they will be held at the ankle of the king.

The Sovereign’s ring will be placed on his fourth finger. The ring has the cross of St George at the centre formed from five rubies, overlaying an octagonal cut sapphire and bordered with fourteen old cushion cut diamonds. The ring was originally made by Royal Goldsmiths and Silversmiths Rundell, Bridge and Rundell for the coronation of William IV. It is said to be a symbol of ‘kingly dignity’.

The coronation sword, also known as The Jewelled Sword of Offering, will be presented by the archbishop, who first blesses the sword and then presents it with the direction that it should be used for the protection of the good and the punishment of evil. First used in 1821 by George IV, it has been used at all coronations since 1902. Like the Sovereign’s ring, the sword, made from blued steel, with a gold, jewel encrusted hilt and jewelled leather scabbard, was a commission from Rundell Bridge and Rundell.

The ceremony culminates with the placing of the St Edward’s Crown on the monarch’s head, the actual ‘coronation’.

The new King will change his crown for The Imperial State Crown as he leaves the Abbey. This is the crown that he will wear for future state occasions like the annual opening of Parliament. Although set in gold with 2,868 diamonds, 269 pearls, 17 sapphires, 11 emeralds and four rubies, it weighs a mere 2.3lb and is a more practical choice. It was worn by the Queen when she left Westminster Abbey in 1953. It was originally made for the coronation of her father, King George VI, in 1937.

Many of us grew up listening to older relatives tell tales of the Queen’s coronation. Televisions were purchased for the first time for the occasion, families huddled round radios to hear the ceremony live, and there is the enduring account of Queen Salote Tupou III who refused to be cowed by the rain and rode through London in an open topped carriage. No doubt King Charles’s coronation will be a different meld of old, new and unexpected acts of generosity and kindness. We can but wish for a day of joy and hope, amidst the tradition and ceremony.

Fluctuations of the market in the last few years

Posted on by

As with every market, jewellery prices will inevitably fluctuate, though I can’t say I’ve seen the price of precious stones go down in the last few years. Seen as a commodity by some and as a treasure by others, it’s important to understand the cost of remaking a unique piece of jewellery. It will be dictated by global demand for diamond (or other precious stones), gold, silver, palladium and other alloy metals and stones.

High worldwide demand for palladium – due to its key importance in the development of renewable energy – inevitably increases the cost of gold – based items of jewellery. Because of its softness, gold used in jewellery is mixed with alloys. Alloys are other metals, such as zinc, copper, nickel, iron, cadmium, aluminium, silver, platinum and palladium. This mix then alters its appearance, hardness and melting point. Palladium is a chosen favourite as an alloy metal. At today’s value, the scrap value for palladium is £41/gram compared to £21.50/gram for platinum, which then impacts gold jewellery pieces.

As an example, this 9ct gold gate bracelet with heart locket was estimated £70-£100 by Bonhams in 2005. Today’s estimate would most likely be £200-£300.

Designer pieces with diamonds are affected in a similar manner.

This diamond and gold bracelet by Kutchinsky (above) sold at Bonhams for £1,553 (including premium) in 2005.

A similar item by the same designer (below) sold for £2,550 (including premium) in 2019.

For insurance purpose, the above bracelet would receive a value of £8,000 as at 2022.

Coloured stones have also seen an increase in price.

This emerald and diamond cluster ring is set with an emerald weighing approximately 5.20 carats and approximately 1.15 carats of diamonds. It was previously valued at £42,000 in 2011 for insurance purpose. Eleven years on, it is now valued at £65,000.

One could try to apply generic inflation percentages as a tool to update valuations, however this is incorrect and will often lead to your jewellery being under or overvalued. In the case of the above ring, a formula trying to reflect inflation would be detrimental to the value of the ring.

Valuing jewellery should always be case by case, as some signed vintage pieces will increase over the years, but not at the same rate as precious gemstones for example. The market for an Art Déco Cartier wristwatch (as below), though rare, has a smaller market of potential buyers and sellers. Comparatively to coloured stones, the value for this wristwatch will never exceed a certain plateau. This watch currently retails for £35,000.

A similar wristwatch by Cartier (below) sold at Bonhams in 2017 for £16,250 (including premium) and would have most likely received an insurance value of £23,000.

Diamonds on the other hand continue to escalate at a steady pace.

These diamonds earstuds (above) are 4.01 carats and 4.04 carats respectively. They were valued for insurance purposes at £300,000 in 2012 and are now valued at £360,000.

The same applies to contemporary signed pieces such as the Alhambra collection by Van Cleef & Arpels.

The mother-of-pearl Alhambra necklace by Van Cleef & Arpels was sold for £9,950 less than ten years ago and now retails for £15,800. A steady increase reflecting world demand for durable contemporary and elegant jewellery by a reputable designer.

The jewellery market is not exempt from worldwide affairs and economic changes, but it will always have an added unquantifiable value: emotional value. Jewellery can be seen as an investment, but it still predominantly remains a purchase of pleasure and luxury, whichever gem or metal one chooses and whatever happens in the world.

The French Crown Jewels – Transformations and Fate of The Collection

Louis XV did not add to the collection but instead had stones recut. He especially had the Côte-de-Bretagne recut in the shape of a dragon to be set in the Golden Fleece. By recutting it, the stone now weighs almost half of what it did.

Replica of the Golden Fleece

The Côte-de-Bretagne and the Golden fleece are amongst the very few pieces ever to be found after the great theft of 1792. Over the course of a few days, thousands of jewels,tapestries and furniture was stolen at the Hotel de la Marine, the royal storage since 1775. No one knows who exactly is responsible for the heist and accusations were made against everyone. Many were executed by guillotine, which had been moved in front of the Hotel de la Marine as a statement. Other thieves survived by revealing the whereabouts of the jewels and furniture. The Sancy and blue diamond were lost, but the Côte-de-Bretagne was found in Holland, where it was recut and sold in England. It was later brought back to France along with the Regent.

Napoleon added to the collection over the years.

In 1814, when Louis XVIII came to power, the crown jewels counted 65,072 stones and pearls: 57,771 diamonds, 5,630 pearls, 1,671 coloured stones (424 rubies, 66 sapphires, 57emeralds, 235 amethysts, 547 turquoise, 24 cameos, 14 opals and 89 topaz).

Charles X had some diamonds set in a sword. The sword was modified by Napoleon III, by adding bee motifs and number III. It was stolen from the Louvre in 1976 remains lost to this day.
During the III Republic, the Crown jewels were exhibited at the Exposition Universelle in 1878 and again in 1887 at the Louvre. In 1882 a vote was put forward by Benjamin Raspail to decommission the Crown jewels to be sold and dispersed. The Republic wanted nothing to do with Royalty. The vote was 325 yes against 85 no. Luckily the Regent and Côte-de-Bretagne were given to the Louvre and the Musée des Mines.

The Crown jewels were offered for sale a few years later in 1887 over the course of 9 sessions at the Louvre. The sale was a success for the government but a historical and gemmological disaster. Gems were unset so none would be traceable to a particular monarch or piece of jewellery. The biggest buyers were Boucheron, Tiffany and Van Cleef. Bapst Frères also purchased many in order to keep the gems in France.

Tiffany sold many pieces to American heiress who wanted a piece of history and French aristocracy. William Waldorf Astor purchased the Sancy and donated it to the Louvre. Over the last 70 years, the Louvre has tried to buy back as many pieces as possible. There are currently 23 pieces in the Apollo Gallery.
