K is for Kyanite

Posted on by

Introduction

K is for – Kyanite, a gemstone which is more frequently being used in modern jewellery and is a favourite of designers such a Pippa Small. But what is this beautiful blue stone and what do you need to know about caring for it?

Colour

Sometimes mistaken for sapphire, kyanite was named in 1789 by Abraham Gottlieb Werner and is derived from the Greek word ‘kyanos’ which is in reference to its typically blue hue though it can also be found in other colours including green, grey and rarely yellow, pink and orange. A strongly pleochroic material, kyanite is a trichroic stone meaning three distinct colours can be seen depending on orientation though our eyes only allow us to distinguish two at a time. The orange variety often has weak pleochroism. Most material has a ‘glass-like’ vitreous or pearly lustre and is transparent to translucent.

Chemistry and Localities

Kyanite is an aluminium silicate mineral (Al2SiO5) and belongs to the triclinic crystal system, most commonly forming in sprays of blade-like crystals but distinct euhedral crystals can also be found and are highly prized by gem crystal collectors as specimens. Kyanite is the high-pressure preferring polymorph of the minerals Andalusite and Sillimanite, which means that the three minerals have the same chemical composition but different crystal systems. The most significant localities are Kenya, Mozambique, Madagascar and the USA.

Use as a Gemstone

Kyanite is difficult to facet and polish due to its perfect cleavage and differential hardness. When cut parallel to the c-axis (direction of growth), it has a hardness of 4 to 4.5 but when cut perpendicular to the c-axis, it has a hardness of 6 to 7.5. Whilst some material may be relatively free from inclusions, most kyanite seen in jewellery will be included or colourzoned. This is especially true of larger stones. A rare phenomenon called chatoyancy or ‘cat’s-eye’ has been reportedly found in some kyanites when cut en cabochon.

Due to its variable hardness and brittle nature, kyanite is not particularly suitable for wearing in rings or bracelets and a protective collet setting is preferable to minimise damage from wear. It is suitable for other jewellery items such as earrings and pendants which are less likely to encounter wear and tear of the stones.

Care should be taken when cleaning kyanite and they should not be placed in an ultrasonic or steam cleaner. Instead, a soft brush (a baby’s toothbrush is perfect) with some warm soapy water is recommended.

Other Uses

Kyanite is also used in refractory and ceramic products like high-refractory strength porcelain and other porcelains such as dentures and bathroom fixtures. Its resistance to heat also makes it useful in the manufacture of cutting wheels, insulators and abrasives.

Gem Testing

Although it was previously mentioned that kyanite could be visually mistaken for sapphire, gemmological testing easily confirms the identification of these materials. Kyanite has a refractive index of 1.710 to 1.735 whereas sapphire has a refractive index of 1.76 to 1.77. A difference in optical character along with specific gravity testing also distinguishes between the two.

Value

Lower quality, heavily included material can be purchased for a mere few pounds (GBP) per carat but cleaner, higher quality blue stones and rarer coloured kyanites can achieve hundreds of pounds per carat.

Princess Catherine’s jewellery

Posted on by

From Everyday Mum To Future Queen, A Jewel For Every Occasion

It all started with a proposal…

One of the most famous items of jewellery the Princess of Wales has come to possess, is the “Royal Blue” sapphire engagement ring, which belonged to her mother-in-law, the late Princess Diana. It is probably the most famous sapphire, weighing 12 carats and set within a surround of brilliant-cut diamonds.

In 1981, chosen by the then Prince Charles, for Diana, from the official royal jewellers Garrard, the sapphire ring cost £50,000. Because of the provenance and history of the ring, it has become a priceless piece of jewellery, but one could estimate its current price to be around £500,000.

The world’s most expensive sapphire to sell at auction was sold at Sotheby’s Hong Kong on the 7th October 2015. It weighed 27.68 carats of natural Kashmir origin and made $6,702,564, $242,415 per carat.

For her wedding, Queen Elizabeth II lent the Cartier Halo Tiara to the Duchess. It was made in 1936 and comprises of 739 brilliant-cut diamonds and 149 baguette-cut diamonds, and it was purchased by King George VI (then still Duke of York) for his wife, Elizabeth (who we all know better as the Queen Mother), which she wore to a charity ball at Claridge’s in London, their first gala outing since the official ending of the lengthy court mourning period for the late King George V.

To match Catherine’s engagement ring, the Duke of Cambridge gifted a pair of sapphire and diamond cluster earrings from his mother’s personal collection. The Princess simply had them altered to be drops rather than clips.

The Princess is often seen combining her engagement ring with a classic 33mm Cartier Ballon Bleu wristwatch. Mounted in stainless steel, it is decorated with Roman numerals, fluted crown with a synthetic spinel cabochon, silvered guilloché opaline dial, blued-steel sword-shaped hands, sapphire crystal and steel bracelet. It currently retails for £5,400.

When Catherine gave birth to Prince George, Prince William gifted her the Eclipse diamond ring by Annoushka. It is set with 0.23ct total of diamonds and retails at £1,500.

She wears it in combination with her engagement ring.

For the arrival of Princess Charlotte, the then Duke of Cambridge this time choose another designer, Kiki McDonough, and gifted the Duchess a pair of green tourmaline and green amethyst drop earrings.

She was first spotted wearing these during the couple’s tour of India in 2016. Though these were made-to-order for the Princess, you can currently get a pair of similar earrings (below) from the designer for £3,700. These are green amethyst and diamond earrings, mounted in yellow gold.

The Princess owns several pieces by the designer: 18 pairs of earrings and three necklace to date.

Here are some examples:

The Princess has jewellery for every occasion, as can be expected. Her everyday jewels include the above by designer jewellers, but Catherine also favours high street jewellery, such as the below by Accesorize.

These are no longer available but can be found on eBay ranging from £48 to a whopping £96.96 (plus £10.77 for postage!).

It was rumoured that when Prince Louis was born, the Prince gave Catherine a citrine ring, but it was discovered by fans that the Princess had previously worn it in 2008 while celebrating her birthday.

The ring is beautiful and has meaning for the Princess. She was also seen wearing it for the premiere of the last James Bond film, No Time to Die, to match the golden sequinned gown by Jenny Packham.

Perhaps my favourite dress worn by the Princess.

When the Princess is not at a red carpet event or formal gala, the mother of three has been seen to wear a necklace by Spells of Love retailing for £85, suspending three medallions with the initial of each child.

Catherine also wears a Merci Maman necklace gifted to her by her sister, Pippa, after the birth of Prince George in 2014.

For more formal wear, the Princess has been seen wearing brooches, tiaras and exceptional necklaces, such as the four-row pearl chocker, created using a collection of cultured pearls gifted to the Queen by the Japanese government which Catherine wore to Prince Philip’s funeral in April, 2021. In mourning, the Royals don’t wear colour, so pearls are pure, white, and unflashy. This tradition comes from Queen Victoria, who did not want to wear any colour following the death of her husband Prince Albert.

The late Princess Diana also wore it to a state banquet in the Netherlands.

A very sombre then Duchess of Cambridge wore the historical chocker for the Queen’s funeral earlier this year.

The Princess combined the tiara worn by the late Princess Diana (above) with her engagement ring of course but also the Royal Family Order brooch, representing the late Monarch within a diamond surround.

The tiara, called the Lover’s Knot tiara, was lent to Diana as seen below, then went back to the Queen, and upon her passing, is now worn exclusively by Princess Catherine.

Several of Queen Elizabeth’s II jewels will have been passed down to the Queen Consort and several to Catherine.

Recently, the Princess wowed us with this stunning emerald and diamond choker. She stepped out at the Earthshot Prize Awards in Boston in a bright green gown by Solace London, paired with an emerald-and-diamond choker, once owned by Princess Diana. The choker itself was first owned by Queen Mary in 1911, and later presented to Diana as a wedding gift to Prince Charles in 1981.

In this year’s Christmas pictures, the Princess wears a pair of ruby and diamond cluster earrings, made by Soru in Turkey, and retail for £145.

Whatever the occasion, Princess Catherine never disappoints with her exquisite outfits and matching jewellery. And on this special occasion, I wish her a very Happy Birthday.

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.

Hocus pocus… Focus on… Amber

Posted on by

To kick off this mini series of Halloween gems, amber is the chosen first. What could be more spooky than trapped insect containing deadly bacteria…

Prized for its deep rich and warm orange hue, amber is an organic gem, meaning that it is created from living or once living organism, it is fossilized tree resin dating tens of millions of years. It is composed of carbon, oxygen and hydrogen. Nicknamed “the gold of the North”, it is most commonly found on Northern Europe’s beaches, washed away with the ocean tides. It can also be dug from the ground and deposits have also been found in the Dominican Republic, Myanmar (Burma) and Mexico.

There is a distinction to be made between amber and copal amber. The latter refers to amber which fossilized less than a million years ago. But who’s counting!! It is also fossilized tree resin and is formed in the same manner. One cannot differentiate between the two using a magnifying glass, but rather by using “granny’s old tricks”. Some say that rubbing copal amber on the heel of your hand will emit a smell, others suggest a drop of acetone or even gasoline to determine copal from mature amber: amber is unaffected by acetone whereas copal softens the material. Either way, probably best to avoid doing at home and damaging one’s precious jewel!

Like with all gems, it takes very specific conditions to create amber. It takes a few million years for resin to harden. Once it has hardened it lays under sediment in an oxygen-free environment. It turns to copal amber. It then takes a few more million years to become more stable with the effects of heat and pressure applied to the copal amber to become amber. Research shows that the deposits found in the Baltic and Dominican Republic came from extended immersion under seawater.

Because of its relative softness – rating at 2/2.5 on the Mohs scale (talc powder rates at 1) – it is not commonly cut with facets, but rather polished into beads or free-form pieces.

Jewellery made of amber tend to be big pieces. The reason for it being the lightness of this gem, making it a perfect candidate to wear around one’s neck without feeling weighed down.

The most prized amber pieces are typically transparent, dark reddish hue. However, amber also comes in white and treatments to enhance colour can modify its appearance totally. Heat treatment and dying are commonly used to enhance amber and one distinct mark to look for are sun spangles. Heating amber can cause fracture-like marks: sun spangles.

Amber is a treasured gem because of the secrets they can unveil. The insects, fauna and animals they have sometimes captured tell a tale.

Inclusions play a huge part in the final value of amber but often if the inclusion is perfect, then it probably is too perfect to be real.

It can be extremely difficult to trust authentic amber with inclusions, such as this piece for sale on eBay for $129,000:

And this perfectly preserved scorpion, also on for sale at eBay for £4.90! :

When in doubt and spending a large amount, always ask for a report from a reputable laboratory.

Man-made or real, amber with insect inclusions make the perfect jewellery piece for trick or treating!

Hocus pocus… Focus on… Skull Jewellery

Skull jewellery and gemstones

Skulls. Usually not what comes to mind when talking about jewellery design and carved gems. However, skull jewels, and especially rings, have had a long tradition of being part of one’s collection.

The appeal may not be so obvious but it is one that continues to be popular throughout times.

Why a skull? It acts as a reminder. That life is not forever and days are counted. That one should live every day to the fullest, carpe diem. And what’s not to love about that message? Embracing one’s life and accepting your fate, not always fighting against the things we cannot control.

In more recent years, Theo Fennell is recognised as one of the top fashion jewellers to use this symbol of life and has used all sorts of gemstones in his creations to amplify his creations.

If rings are not your go to jewellery item this Halloween, then perhaps a pendant necklace by the same designer could be an option.

Halloween calls for creativity, so this year, why not trade in the pumpkin for a carved gem skull? Sure to get your neighbours quivering in their boots and make a bold statement.

There are a multitude of options. In keeping with the orange theme of the pumpkin, a citrine skull could be an option.

Quartz, which citrine is a variety of, has a hardness of 7/7.5 on the Mohs scale and makes it a good candidate to get sharp edges to carve the teeth and a pointy nose.

It can also come other colours such as purple amethyst:

Or even blue:

A wide variety of options is available on the market, including at specialized auctions.

Bonhams sold this lot in Los Angeles in 2017 for $1,187 incl premium. It includes an amethyst obelisk decorated with twenty carved skulls, Height 11in; a sculpture comprising three skulls with a butterfly, carved of boulder opal from Queensland, Australia, length 5 1/2 in; together with a Mexican black obsidian carving of a skull with owl perched, height 6 1/2 in.

But possibly the most “out of this world” carved skull must be a sculpture sold in 2015 at Bonhams in Los Angeles, carved out of meteorite, making it the largest Gibeon meteorite carving in the world.

Gibeon meteorites are iron-based and “originated billions of years ago from unstable planet that existed briefly between Jupiter and Mars.

When the planet broke apart, a section of its core travelled through space for four billion years.” It penetrated the Earth’s atmosphere about 1,000 years ago and landed in Namibia.

This particular 21kgs life-sized carving, nicknamed Yorick, was created from a 280kgs meteorite. It is one of the rarest forms of meteorite.

The choice is vast for Halloween decorations whether for the house or fashionwear. All one needs to do now is pick the right outfit for a night of trick or treating…

Ametrine

Posted on by

Ametrine is a form of quartz. It combines both the purple amethyst and the yellow citrine all into one stone, making it somewhat of a unique specimen. To add to this uniqueness, commercial ametrine is only found in Bolivia, and more precisely in the mine of Anahi.

What do we mean by commercial? Stones that are of a particular quality that can be cut and set into jewellery.

The mine was named after a legendary princess of the 1600s who married a Spanish conquistador and was given the mine as dowry. The mine located in a very remote area of Bolivia, was lost for centuries. Research shows that the mine was only rediscovered in the mid-50s, only accessible by plane and small boats.

Ametrine displays the same properties as amethystand citrine. Ametrine rates a 7/10 on the Mohs scale. The Mohs scale of mineral hardness was created by Friedrich Mohs in 1822 and determines the scratch resistance of minerals when scratches by another mineral.

The Mohs scale is used to manufacture everyday objects: your mobile phone’s screen glass is made of a material that scratches at level 6, some at level 7. Ametrine therefore has good toughness and is suitable to be set in jewellery, such as this sapphire and ametrine torsade necklace which sold at auction for $408 (pictured below).

It can be noticed that ametrine is most commonly found in jewellery as a rectangular-cut stone. This cut displays the bi-colour property of the gem, exposing both colours at its best, with the clear demarcation between the yellow and the purple. The most prized ametrine will display fine transparency, a good contrast of colours and an equal balance between the two colours. Though it rates rather high on the Mohs scale, its colour can fade if exposed for long periods of time to too much bright light. If ametrine is worn in jewellery, its wearer should be aware of its possibility to scratch and chip if not cared for properly.

How would one care for its ametrine-set jewels? The best and safest way to clean your jewellery is with good old fashion soap and warm water and not exposing it to high heat. It is preferable not to place the gem in an ultrasonic in case the stone or others in the piece of jewellery have been dyed or fracture filled (the machine’s vibrations will remove the modifications).

Because of its extraordinary features, ametrine is often carved into fantasy-cuts.

An ametrine carving of rooster by Gerd Dreher sold at auction for $12,575. Dreher is a German animal figure carver, the fourth generation of Dr eher in this line of activity. He was born in 1943 in Idar- Oberstein, one of the most important gemstone centres in the world with the finest lapidaries and gem cutters.

This gem-set obelisk / jewellery box by Manfred Wild (pictured top right) remained unsold at $200,000- 250,000. Wild aas born in 1944 in Kirshvayler near Idar-Oberstein. He is the eighth representative of the family dynasty that has been engaged in lapidary art since 1630. Manfred Wild is sometimes called “The 21st century Fabergé”.

Ametrine is used in a wide range of carvings for its intriguing features. It is not uncommon to see jewels set with ametrine but it seems to be slightly underappreciated for what it is: an exceptional wonder of nature who combines two stones into one giving it a delightful play with colours.

I is for iolite

Posted on by

Iolite is the gemstone variety of cordierite, a magnesium, iron, aluminium and cyclosilicate mineral named after the French geologist Pierre Cordier (1777 – 1861) – founder of the French Geological Society.

As with some other blue gemstones, iolite is known for its pleochroic properties giving it that extra sparkle. Pleochroism is an optical phenomenon in which a substance has different colours when observed at different angles, especially with polarized light.

Iolite occurs in several areas of Africa, including Kenya and central Tanzania. In fact, when Tanzanite was first discovered, geologists thought it was corderite.

Other iolite source countries include India, Brazil, Norway and a large deposit found in 1994 in Madagascar.

The name iolite comes from the Greek word ios, meaning “violet”. It is said that iolite slices were used by Viking navigators to locate the sun on cloudy days, used as some form of compass.

The gem rates at 7 to 7.5/10 on the Mohs hardness scale. The Mohs scale of mineral hardness was created by Friedrich Mohs in 1822 and determines the scratch resistance of minerals when scratches by another mineral.

The Mohs scale is used to manufacture everyday objects: your mobile phone’s screen glass is made of a material that scratches at level 6, some at level 7.

Even though iolite scores rather high on the Mohs scale, it has strong cleavage in one direction, giving it only a fair toughness. Cleavage, caused by weak atomic bonds, is the weakest plane in a gemstone where the gemstone can split.

For this reason, jewellers are a little reluctant to use the gem in jewellery, specially any hard-wearing jewel such as rings for example.

The gem’s most sought after colours are violetish blue to fine blue. But iolite can appear to be greyish, even transparent, or golden and even brown. Depending on where the light hits, differentcolours will show. For this reason, iolite can be confused with colour change sapphires.

Vivid violetish iolites over 5 carats are rare and cannot be treated in the same way as corundum (sapphires) can be. Unlike sapphires, iolite’s chemical composition won’t allow it to be heat treated to intensify its colour. The gem would simply melt at such high temperatures.

Iolite is more often than not faceted, bringing out its unique transparency, free of inclusions.

But it also is a popular choice for cabochons.

In some iolites, a phenomenon called cat’s eye can sometimes be observed. This effect comes out at its best when the gem is cut as a cabochon.

The cat’s eye effect is caused by long, parallel, tubular inclusions. It can also be found in other gems such as sapphire and chrysoberyl.

Though iolite is hardly ever treated, making it a very appealing affordable blue-gem alternative, due to its relative hardness and lack of consistent fine quality supply, it is not found in as many workshops as tanzanites for example. However, iolite is also cut as beads and strung to make beautiful colourful
necklaces.

A wonderful twenty-first wedding anniversary gift…

The Imperial State Crown

Posted on by

If one wants a glimpse of The Imperial State Crown, it is on display in the Jewel House at the Tower of London, as it has been for the last 600 years. But on the 19th September 2022, this most unique and priceless item of jewellery laid on her Majesty The Queen Elizabeth II’s coffin for her final farewell.

Imperial State Crown

During her reign, Queen Elizabeth II would wear it annually for the State Opening of Parliament, sharing in 2018 that “You can’t look down to read the speech, you have to take the speech up, because if you did your neck would break”. The crown weighs 1.06kgs.

Queen Elizabeth wearing the Imperial State Crown

Monarchs wear the Imperial State Crown when departing from the Abbey after the coronation, and for all other occasions requiring crown-wearing thereafter.

Originally made by Rundell and Bridge in 1838 for the coronation of Queen Victoria. It was commissioned for the coronation of the Queen’s father, King George VI in 1937 from Garrard & Co.

The crown is set with historical gems with nearly 3,000 stones – including 2,868 diamonds, 273 pearls, 17 sapphires, 11 emeralds, and five rubies.

The Culinan II, or Second Star of Africa, weighs 317.4 carats, with 66 facets.

Cullinan produced 9 major stones of 1,055.89 carats in total, including the Cullinan II, plus 96 smaller brilliant and some unpolished fragments weighing 19.5 carats. The Cullinan diamond was found in 1905 in South Africa’s Premier Mine at Cullinan, named after Sir Thomas Cullinan, who opened the mine in 1902. It is believed the diamond surfaced 1.18 billion years ago. Originally thought to be some priceless crystal, the mine’s manager did not give another look when the miner found it. He persevered, and it then became the largest diamond to be found.

It was sent to London in a plain box via registered post and presented to King Edward VII. It remained unsold until 1907.

The Transvaal Colony government bought the diamond on 17 October 1907 for £150,000, the equivalent of £18 million. It was presented to the King on his 66th birthday at Sandringham House.

He accepted the gift “for myself and my successors” and ensured that “this great and unique diamond be kept and preserved among the historic jewels which form the heirlooms of the Crown”

The king chose Joseph Asscher & Co. of Amsterdam to cleave and polish the rough stone into brilliant gems of various cuts and sizes.

Cutters here in Amsterdam plan how the stone should be cut. It took 8 ½ months to cleave and cut.

The images above show Joseph Asscher cleaving the Cullinan.

On the first blow, Asscher’s hammer blew off. It was on the second attempt that the diamond shattered into 9 pieces.

Cullinan I is set in the sceptre, which also laid on the Queen’s coffin.

The Black Prince’s ruby, in its prominent place on the crown, is in fact a spinel. It was only in 1783 that spinels were differentiated from rubies. They share many chemical properties, such as aluminium, oxygen, and chromium but spinels also have magnesium.

This “ruby” is said to have been in English royal hands since the 1360s.

It was probably discovered in the Himalayan mountains of central Asia, in the Badakhshan (Balascia) region that was famed for its spinels. It drilled at some point to be worn as a pendant. The hole was later filled with a smaller cabochon ruby edged in gold.

It was supposedly worn by King Henry V at the Battle of Agincourt in 1415 and saved him from an axe blow to the head, struck by the Duke of Alençon. Henry survived, as did the ruby, and the English were victorious.

The Stuart Sapphire is set at the back of the crown and weighs approximately 104 carats.

In Youngblood and Davenport “The Crown Jewels of England”, they describe the stone as follows: “oval in shape, about one and a half inches in length, by one inch in breadth, and is set in a gold brooch. It has one or two blemishes, but is of good colour, and was evidently deemed of high value by the Stuarts. At one end has been drilled a hole, probably to introduce some attachment by which the stone could be worn as a pendant.”

Queen Victoria, was the first monarch to have the sapphire set in her state crown. During Victoria’s reign, the sapphire was set at the front of the crown, just below the Black Prince’s Ruby.

After the discovery of the Cullinan diamond, the sapphire was relocated to the back. There is still some mystery as to whether the Stuart sapphire in The Imperial State Crown has been the same gem since it was first used in royal jewels in 1660 but it certainly has been in the collection for over two centuries.

These priceless gems, the Cullinan II, the Black Prince’s Ruby and the Stuart Sapphire are a reminder of majesty, sovereignty and tradition embodied in the institution. Following tradition, King Charles III will wear the St Edward’s Crown for his coronation, but will put on the Imperial State Crown to leave Westminster Abbey at the end of the ceremony.

God Save the Queen, Long Live the King.

The one that got away…

Posted on by

I don’t recall the life-changing opportunity that was missed; perhaps that’s just as well. It would be galling to know that one had passed up an opportunity to buy something that went on to make multiple times the purchase price.

I do remember seeing two wonderful pairs of enamel cufflinks being sold very inexpensively at an antiques fair. The seller was insistent that he would only accept cash, and as I didn’t have that sum of money on me I asked him to hold them whilst I went to a cash point. When I returned, having extracted the maximum possible from three bank accounts, he nonchalantly informed me he’d sold them to someone else. Hard money on the spot clearly talks.

I also remember the insurance valuation I did for a couple who had recently downsized. Referring to a previous valuation schedule I queried the whereabouts of an impressive Victorian inkstand by a well-regarded maker. They informed me that they had had to dispose of a great deal in the move and they had sent the inkstand to a local charity shop, believing it to be silver plate and of little consequence. They were stoic about the discovery. No point in crying over spilt ink!

What has got away from me is trends. I wish I could have called the rise and fall of gold prices better. If only I’d known that as cigarette smoking fell from grace, there would be an unexpected rise in the popularity of cigars and cigar related memorabilia. Thirty odd years ago American Marvin R. Shanken launched Cigar Aficionado, and this venture set off perhaps the most unforeseen social craze of the 1990s — the renaissance of cigars and an explosion in the popularity of all cigar-related paraphernalia. This too has now largely fallen away.

One of my career-long passions has been cufflinks. I have supplied literally thousands of pairs of antique and vintage cufflinks to organisations both here and in America. I’ve constantly been told that they would be going out of fashion and that no one would want the bother of double cuffed shirts anymore. However, even as the tie has fallen from grace, the tailored shirt has remained a wardrobe staple and notwithstanding the hiatus of the pandemic cufflink sales are on rise again as workers return to offices. I have just sourced an Art Deco dress set for a well-known film franchise that wanted the genuine article and not a modern copy. I’m really glad that one didn’t get away.

The great thing about our world is that there is always tomorrow. There is endless speculation about where trends are going and what individual pieces might make. It’s one of the things that makes the art world so interesting. We all bring our expertise to bear on determining accurate prices, but the marketplace can be capricious and that’s what makes it exciting. Fashions come and go, and unexpected left-field shifts like the rise of NFTs can cause a significant change in thinking. Being able to foresee these repositioning of market forces would be a really useful superpower.

Eventually, most people are pragmatic about missed opportunities, which sometimes presents a chance to rethink and learn. I have a huge collection of single cufflinks that are partnerless. I shall let you decide if this collection should be viewed as the ones that got away or the ones that were saved. I prefer to think of them in the latter category, however, I’d be overjoyed to find their partners and restore the marriages.
