Castellani Micromosaic Brooch

Jewellery Pick of the week – Castellani Micromosaic Brooch

Posted on by

This week’s pick is an extraordinary micromosaic brooch by Castellani I had the delight of discovering in an inherited collection. Much to our surprise, amongst the treasured and loved jewellery was an original box containing this perfectly well kept brooch. The brooch is circular and set throughout with blue and red micromosaic, in closed-back setting, only 3cm in diameter.

So why is it so special?

Firstly due to its age. Dating from the 1860s, it is extremely rare to not miss at least one tesserae in a micromosaic piece, let alone one that has been around for 170 years.

The above brooch was sold at Christie’s in 2011 for Euro 31,040, against an estimate of Euro 8,000-12,000, and had a missing tile.

No dents are present in the item’s soft gold, which is another key aspect of its uniqueness.

And it is also signed on the back with a double C (no Chanel was not the first one to use a double C as a maker’s mark!).

Castellani’s founder, Fortunato Pio Castellani, opened up shop in Rome in 1814 and is commonly described as launching the archaeological revival movement in jewellery. This passion came a few years after opening his shop, hearing his friend Michaelango Caetani speak about recreating gold to look ancient. With the opening of the Etruscan Regolini- Galassi tombs in 1836, Castellani was granted access to view the jewellery. With further fascination for archaeological finds, Castellani’s jewellery became more and more popular.

Using various exquisite techniques, such as wiring and granulation, Castellani was able to imitate ancient jewellery. The week’s brooch has a ropetwist border, adding to it a sense of completion.

So what’s the price tag on such a rare piece?

At auction, the item would be valued at £1,500-2,500. A similar example sold for £2,375 including premium in 2018 at Bonhams. It was orange on a blue background.

Another piece is currently for sale privately for over £18,000. This brooch is blue and green.

And though I was able to find two almost identical pieces for sale, over a decade separates their sale date. Which goes to show how rare brooches of this style and make are. If you find one… Grab it and keep the box!

This week’s pick – Trooping the Colour and Princess Catherine

Posted on by

What fan of Princess Catherine would I be if this week’s pick didn’t focus on her one-off appearance for the King’s birthday?

Princess Catherine delighted the nation on the 15th June by attending the celebrations. With her family by her side and gleaming smile, I don’t think anyone could tell she was undergoing any treatment.

She wore a Jenny Packham dress, reworked from last year’s coronation.

Long-sleeved with thin black piping at the waist and an oversized bow on her lapel, she completed the look with a white Philip Treacy headpiece, white pumps and a black clutch.

As for the jewellery, the Princess of Wales wore Cassandra Goad Cavolfiore earrings in 18ct yellow gold, set with 2mm white cultured pearls and approximately 0.30ct of diamonds. These retail for £5,620.

One could accentuate the look with the matching Carioca cuff bracelet by Cassandra Goad, retailing for £9,580.

As a Colonel of Irish Guards, the Princess added to her jewels, the Irish Guards Regimental brooch.

The Irish Guards, to whom the Princess wrote a letter wishing them good luck for the event and to let them know how proud she was of them, were among the British troops participating in the parade.

Little fact about this year’s Trooping of the Colour: for the first time in more than 100 years, soldiers on parade were allowed to have beards, approved by the King earlier this year and which applies across the Army.

The Princess has once again shown how devoted and courageous she is: being scrutinised by millions during these times could certainly not have been easy. But, let’s be honest, she smashed it! My only glamour during my treatment was putting on my wig for very special occasions!

Though delighted to see the Princess at a public event, she has warned she is “not out of the woods yet” and it will be some time before she makes another appearance.

Until her treatment is over, I wish her and all those affected by the disease much strength.

The Trooping of the Colour marks the official birthday of the British Sovereign and has been celebrated in June for over 260 years.

Over 1400 parading soldiers, 200 horses and 400 musicians participate, together with an RAF fly-past.

The operational soldiers wear the ceremonial uniform of red tunics and bearskin hats and are inspected by the Sovereign once they reach Horse Guard’s Parade in Whitehall. The parade moves from Buckingham Palace and down The Mall to Horse Guard’s Parade and carries on to Whitehall.

Pick of the week highlights of the Bonhams jewellery sale

Posted on by

I had the pleasure of viewing the upcoming jewellery sale at Bonhams on New Bond Street this week. I received such a warm greeting from an old colleague at the front desk, and proceeded to head to the viewing room. Now, some might say they are too scared or intimidated to walk through these halls, let alone have the audacity to look at a jewellery sale on display. But here’s the secret… It’s open to everyone! And you should take advantage of these viewings. Think of it as a free museum entrance with endless exhibitions of exceptional goods, which have been, more often than not, hidden away from the public for generations.

I had the pleasure of being shown some highlights of this 118 lot sale.

These included a pair of Castellani sapphire bracelets from 1865.

These bracelets of Byzantine inspiration really are beautifully made. Castellani is one of the best when it comes to archaeological revival style jewellery and these pieces are no exception. “To have one bracelet is wonderful but to have two is very rare” said Jean Ghika, Global Head of Jewellery. With an estimate of £25,000 – 35,000, I am sure they will find a new home.

Still in the antique jewellery section of the sale are these spectacular “Night and Day” diamond earrings.

Still in their original box, these earrings can be altered depending on the mood. One can wear the diamonds for a dash of dazzle or cover them up with the cannetille beads. It is an extraordinary piece and statement to earlier craftmanship. They have an estimate of £12,000 – 18,000.

It should come as no surprise that my eye was immediately drawn to an early 20th century Cartier piece: an enamel and diamond fob watch circa 1910.

The delicate purple guilloché enamel is highlighted by a central diamond and a diamond border. The reverse is everything that makes Cartier watches: blue steeled hands, engine-turned dial and attention to detail. The very attractive estimate of £6,000 – 8,000 is bound to call out collectors.

Amongst the highlights is a sapphire and diamond cluster ring, circa 1890 with an estimate of £60,000 – 80,000. Why the price tag? That would be due to the origin of the sapphire: Kashmir with no evidence of treatment. Though a little abraided on the facet edges, a quick repolish would restore this stone and ring to its original glamourous state.

This piece shows once more the importance of getting gems certificated, as origin or colour and clarity can affect its value dramatically. This is even more apparent with the “Toi et Moi” blue and pink diamond crossover ring by Mouawad.

Both diamonds weigh a little over 5 carats, natural Fancy Intense Blue colour, VVS2 clarity and natural Fancy Purple-Pink colour, I1 clarity.

Bonhams says: “It is estimated that as little as 1 in 10,000 gem-quality diamonds extracted from the Earth’s crust show noticeable colour and of these stones, an exceedingly small percentage are blue or pink. The majority of these rare marvels of nature are under 2.00 carats in weight and stones exceeding 5.00 carats, are even rarer. Stones with high intensity colour grades such as ‘Fancy Deep’, ‘Fancy Vivid’ and ‘Fancy Intense’ are considered some of the most desirable colour classifications by GIA.” Due to its rarity the estimate for this ring is £1,000,000 – 1,500,000.

The Bonhams London Jewels sale that was held on 13th June garnered extraordinary results, with a total of £6,590,562, with 78% sold by lot.

Jewellery Pick of the Week Cannes Film Festival

Posted on by

It should come as no surprise to those who have read my previous articles that I would have chosen Cannes Film Festival for this week’s pick. A red carpet is always a good opportunity to see some of the most beautiful haute couture and jewellery which are inaccessible to most of us. Today I am looking at jewellery pieces by Tiffany & Co. worn by Camille Cottin – for whom I happen to have written a feature length jewellery heist screenplay.

As Mistress of Ceremony of the 77th Cannes Festival, and ambassador for Tiffany & Co., the spectacular French actress wore Tiffany Edge diamond drop earrings. These are set with 3.27cts of diamonds, mounted in platinum and 18ct yellow gold and retail for £32,800.

That same evening for the gala’s opening dinner, while still adhering to a very chic and elegant style, she sported another Tiffany & Co. suite from the HardWear collection.

Her neck was adorned with the Tiffany HardWear Graduated Link Necklace in yellow gold and pavé diamonds. It retails for £72,500 and is set with 9.07cts of diamonds.

The earrings en suite are set with 1.18cts of diamonds and retail for £15,800.

This particular jewellery line comes in white, yellow and rose gold, and can, as demonstrated the last few days, be worn to any circumstances, it really is a girl’s best friend.

The choice in design from Tiffany & Co. jewellery seems to resonate the theme of this year’s opening ceremony: women at the forefront of film and creativity. Camille Cottin’s speech mentioned #MeToo movement, the extraordinary Meryl Streep was awarded the Palme d’Or after a moving speech by Juliette Binoche, and Greta Gerwig (director of Barbie) was appointed President of the jury, six years after the last female jury president Cate Blanchett, in 2018. The HardWear collection says it all in its name and in its polished smooth and geometric lines. How could a jewellery collection be more perfect to echo both femininity and power.

This Week’s Jewellery Pick

Posted on by

I recently finished the multiple award-winning show The Marvellous Mrs Maisel. And if you haven’t seen it yet, you know what you’ll be doing straight after reading this article!

The main character, Midge Maisel, played to perfection by Rachel Brosnahan is based on Joan Rivers.

Other characters are real, such as Lenny Bruce, others fictional. Created by Amy Sherman-Palladino, it portrays women’s experiences in the mid-20th century, focusing specifically on a young Jewish woman trying it to make it on the comedy scene.

The series is mostly set in the late 50s and 60s and the costume and jewellery are divine. Costume designer Donna Zakowska created a dream wardrobe for all the characters, earning her awards for her creativity.

Not only are the dresses and jewels visually stunning, they add and carry the story, they are a story of their own. Today I will look at the pearls used in the series and especially one set of doublestrand cultured pearls which Mrs Maisel wears for her first official stand-up at the Gaslight Café (a sticky downtown New York club where the great Joan Rivers also performed).

In this moment she experiences great success, slightly undermined by some misogynistic remarks, then put to right by her estranged husband, and the outfit is perfect and effective. A black dress complemented by a pearl necklace.

The double-strand is strung and knotted with 6mm peach cultured pearls. The pearls appear to be uniform in shape, colour and lustre.

And when looking to purchase pearls, these are the most determining factors in assessing pearl necklaces. In this scene, the choice of colour sends the message of softness, being peach and not gold, and also lets us extrapolate that she could become very successful in the future, the pearls being almost golden. Mrs Maisel and her success shine thanks to the peachy colour and also due to the pearls’ lustre. Lustre measures the rate of light reflecting off the surface of the pearl and the sharpness of reflection visible on its surface. We often describe these as poor, fair, good and excellent. The better the lustre, the more radiance and glow they emit.

The pearls are also well matched and round. Their shape in this scene is key. She is trying to make a name for herself in a male dominated industry, all the while maintaining and celebrating her femininity and exposing her marital instability and struggles as a mother. The roundness works brilliantly.

Though the above baroque pearl necklace comes with a generous price tag of £7,500 they would have sent a very different message than perfectly round pearls.

It was common practise to have faux pearls at the time and they were very effective. In today’s market they do not have any value. The costs of cultured pearls vary greatly depending on the factors mentioned above, amongst others. But essentially, their value depends on what they mean and signify to the wearer.

Jewellery Pick of the week – an alligator hinged bangle by Barry Kieselstein-Cord

Posted on by

This week’s pick is a gold piece of jewellery with a lot of character and no gems. An alligator hinged bangle by Barry Kieselstein-Cord from the 1980s.

This bangle is made of 18ct yellow gold and realistically designed as an alligator with detailed teeth, eyes and skin. And it could be yours for £20,000.

It was offered at auction at Christie’s with an estimate of $4,000-6,000 and sold for $16,250, including premium.

So why the price tag? This item is a good example of how premium is added to craftsmanship. The bangle weighs a little over 100grms and has been worked and moulded with great care, attention and exceptional know-how.

Barry Kieselstein-Cord didn’t always work with gold. His first collection, dating 1972, was crafted in sterling silver. When we think of silver jewellery, one of the famous names that come to mind is George Jensen. Barry Kieselstein-Cord’s collection was bought and presented at Jensen’s flagship store on Madison Avenue in New York City (now closed).

He shot to stardom and his jewellery was soon a key accessory to have. Movie stars like Diane Keaton were quick to get their hands on this new stylist’s designs. He also worked closely with Calvin Klein and Helmut Newton.

His brand has extended into handbags over the years and are considered works of art. So much so that The Museum of Fine Arts in Houston exhibits his Alligator Trophy Handbag made in 1992.

He also created belt buckles, which caught the attention of the Spanish bull fighter El Cordobès who purchased a horse-head buckle in the 70s.

Whilst he was working with sterling silver he made a skull necklace for Mick Jagger’s 30th birthday and continues to this day to make iconic pieces. Though access to these is very limited and exclusive.

So if you want a piece of history, keep your eye on auctions and specialised vintage jewellery shops as these pieces are very rare and the market is scarce for these recognisable pieces.

This Week’s Jewellery Pick

Posted on by

This week I saw a lovely collection of antique jewellery, 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 antique 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…

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.

Cartier and Tiffany rocked at the Golden Globes…

Posted on by

“It’s the most wonderful time of the year…” and I don’t mean Christmas. My favourite time of the year is now, for all the red carpet gowns and jewels. So many impressive pieces displayed at this year’s Golden Globes. This year, I take a look at the two usual suspects that never miss: Cartier and Tiffany & Co., both symbols of chic and glamour, using the finest craftsman and precious gems.

One of my all time favourite actresses is Jennifer Lawrence, and she was faultless with her “simple” velvet gown and diamond-set Tiffany & Co. jewels.

The necklace was composed of a series of princess-cut diamonds, suspending to the front an 11 carat diamond pear-shaped drop. Her earrings were decorated with a total of 6 carats of untreated blue sapphire and diamond surround, mounted in platinum and 18 carat yellow gold. She matched these with a diamond ring and nothing too big which could distract from the Dior clutch.

It was a big year for singer/songwriter Dua Lipa, with a nomination for Best Original Song for the Barbie movie.

She dazzled the crowds with a 1962 gold and platinum Tiffany & Co. necklace. It is set throughout with oval, pear and briolette-cut yellow beryls and brilliant-cut diamonds. A similar piece, dating from 1967, sold in June last year, 2023, at Christie’s for USD $189,000, set with approximately 86 brilliant-cut diamonds, weighing 7.00 carats.

The singer completed her look with a yellow sapphire and diamond cluster ring.

Another very talented singer/songwriter is Jon Batiste. He was superb with a few Tiffany & Co. jewels which sparkled on his Dior suit.

The necklace is from the HardWear collection. It is set throughout with fancy links, each set with brilliant-cut diamonds and mounted in 18 carat yellow gold. This necklace currently retails for £70,000. However, there are several other options retailing from £550 mounted in silver, to £215,500 set with diamonds and mounted in rose gold.

A lovely addition to the necklace was the platinum and 18 carat gold Starfish brooch by Jean Schlumberger for Tiffany & Co. It is decorated with a three carat aquamarine and diamond surround. The Starfish collection ranges from silver, selling for £365, to yellow gold, retailing at £3,450.

While Tiffany & Co. draped several artists, Cartier High Jewellery was the brand of choice for actress Julianne Moore.

She wore a spectacular gold and petrified wood necklace of reptile inspiration. Composed of 57 links, each set with white and yellow diamonds.

Echoing that style of individual panels is the Panthère de Cartier necklace set with almost 2,000 white, orange, yellow and brown diamonds, totalling just under 40 carats. A truly unique piece and a statement to Cartier’s savoir-faire.

The Panthère collection has several options of bracelets, watches and necklaces.

The actor Jared Leto, usually known for taking daring fashion risks, wore a simple 18 carat white gold and diamond Panthère de Cartier necklace.

It is set with two emerald eyes, 309 diamonds, weighing a total of 3.24 carats and highlighted by calibré-cut onyx. It currently retails for £78,500.

The Panthère collection is as desirable as ever and Cartier will always be a go to jeweller for any red carpet event.

12 Days of Christmas

Posted on by

In 2014, Sotheby’s sold a copy of ‘Mirth Without Mischief’ for $23,750, dating from 1780 in which the first version of the famous Christmas carol Twelve Days of Christmas appeared for the first time.

Some historians believe it could be French and could have been created as a memory game, to help Christians learn and remember the principles of their faith. Though this could and has been refuted by some, let’s have a look at what is gifted during the Twelve Days of Christmas.

On the first day of Christmas, my true love gave to me a partridge in a pear tree.

Day 2: two turtle doves
Day 3: three French hens
Day 4: four calling birds
Day 5: five gold rings
Day 6: six geese a-laying
Day 7: seven swans a-swimming
Day 8: eight maids a-milking
Day 9: nine ladies dancing
Day 10: 10 lords a-leaping
Day 11: 11 pipers piping
Day 12: 12 drummers drumming

Someone on the internet has very kindly converted what the cost of all those presents would be in today’s currency and this comes to approximately £35,000.

With this budget, here is my choice for what I would wear during the Twelve Days of Christmas.

The Twelve Days start on the 25th December, and in keeping with the festive red and religious aspect of the celebrations, an early 19th Century garnet and pearl cannetille cross pendant, which sold at Bonhams for £1,500.

On the 26th, with the nights still closing in early, a moonstone necklace such as this Edwardian pendant necklace selling for £995, to shimmer and capture all the starlight.

On the 27th, an emerald and diamond three-stone ring, such as the below selling for £2,950 at Fenton to echo the Christmas tree which might be losing a few needles by now…

On the 28th, it always feel like dates have ceased to matter, so as a special reminder, this Rolex DateJust 1601 in stainless steel, selling for £4,400. Discreet and elegant, it is worn as jewellery.

On the 29th, perhaps a night out in a restaurant dreaming of that sky trip would require novelty cufflinks, as these enamel and silver cufflinks by Francis & Deakin, selling for £315.

On the 30th, one will have a quiet night in before the New Year celebrations. It could be a night to remember and remind that wonderful person just how much you love them with a fancy coloured-diamond ring from De Beers. The below cluster ring is set with a 0.52ct fancy yellow diamond, VS1, within a surround and shoulder set with brilliant-cut diamonds and retails for £7,250.

On the 31st, to celebrate the new year offered to us as a gift, one could purchase these vintage Chanel earrings for £1,370 decorated with bows, like a gift to unwrap.

2024 will be the year of the Dragon in Chinese culture. Dragons symbolise courage, power and protection.

Therefore, to start the year, on the 1st January, let us internalise all these elements and choose to wear a dragonset jewel such as the Fabergé Palais Tsarkoye Selo Red Locket with Dragon Surprise by Fabergé, retailing for £12,000.

The 2nd January calls for a quiet cuppa, and how best to accessorise than with Tea for Two bangle by Hermès £485, decorated with enamel.

On the 3rd, perhaps one is gifting the last few presents of the season and this trio of brooches would make a lovely addition to any jewellery collection, sold for only £280 at Dawsons Auctions a few days ago.

The list wouldn’t be complete without referring to The Princess of Wales jewellery. The Princess is one to reuse dresses and outfits so we could certainly get inspired by her look from last year with the goldplated earrings she wore last Christmas from Cezanne, retailing for £100. No one will notice they aren’t sapphires…!

Finally, as we look to the future and the warmer weather to come, on the 5th January I would recommend the mother-of-pearl Sweet Alhambra bracelet by Van Cleef & Arpels, retailing for £1,300. The butterfly motif reminds us that spring is not too far away, and with it the promise of longer days filled with possibilities…

All these gorgeous gifts bring us to a total of £32,855, well within our budget and enough to splurge on that meal, extra gift or trip away. Best Wishes to all.
