FERNANDO JORGE: sensual Brazil meets cool London

Brazilian jeweller Fernando Jorge has unsurprisingly become the wonder boy of the contemporary jewellery scene in just three years since he graduated from St. Martins in London. Fernando landed in Europe with a baggage full of incredibly original drawings, ten years of jewellery experience in Brazil and a unique knowledge of local craftsmen and stones. With this background, it cannot come as a huge surprise that his talent was sotted and recognised almost immediately. He was quickly snapped by iconic agent Valery de Mure and selected for the prestigious Rock Vault group and won the British Fashion Council award in 2012. Besides his well deserved success, the best feature about Fernando is his jewellery. His "fluid" pieces combine semiprecious gemstones like calcite with delicate rose gold snake chain in ultra sensuous designs; the "electric" series is modern glamour in a punk fashion with black gold set with a unique combination of sapphires and blue topaz or all white set in opals. His Gemfields emerald collection combines the best elements of his work so far, the fluid snake chain design with the irregular shaped stones that transmit so much energy to the pieces. And so, one could continue mentioning all of his innovative ideas, like the use of blue john (a rare english stone) in fine jewellery. Most certainly we will be watching!.

CARTIER Mystery Clocks… unveiled

What's Houdini got to do with timepieces? Plenty as it turns out. Not Harry Houdini himself, but the original artist and watch inventor who he took his stage name from. That man is Jean Eugene Robert-Houdin, the man who designed the mystery clock. Houdin was a self-taught magician and engineer who was fascinated by the idea of the disappearing act and sleight of hand tricks. His work involved the use of transparent glass displays and hidden mechanisms that connected to the display of the clocks he built, and won renown for its inventiveness. Many of his clocks involved hiding the gear train within the clock base, which was then connected via a rod or serrated glass or crystal dial to the display, creating the illusion that the clock ran without any additional wheels. During the 19th and early 20th century, mystery clocks were highly popular among the elite, who found it a fascinating design. 

Jean Eugene Robert-Houdin Mystery Clocks c.1850

Originally inspired by the work Jean Eugène Robert-Houdin, the first Mystery Clocks were designed for (Louis) Cartier in 1913 by Maurice Couet and known as the “Model A.” They featured rotating rock crystal discs to which hands were mounted to indicate the hours and minutes. The rock crystal allows the viewer to see right through the clock, which seemingly has no perceptible means for the hands to move. The mechanism by which the crystal discs turn is invisibly powered by gears hidden in the frame of the clock, while the base of the clock conceals the main body of its mechanical movement. For decades the “Pendule Mystérieuses” or “Mystery Clocks” have captured the imagination. The cost and complexity of the mystery clocks has meant that, over the years, few examples have been made and they achieve astronomical prices every time they come out in auction.

The Gemstone Series: Collecting AGATE

The Agate is a semi precious gemstone that was discovered over 3000 years ago by greek philosopher and naturalist Theophrastus, on the shore of the river Achates. It belongs to the mineral family of the Chalcedonies, a type of quartz like Aventurine, Carnelian and Onix. Agate when cut exhibits a series of lines and different colours that make it strikingly attractive. This gemstone has been used in art objects and jewellery for centuries. It was very popular in traditional Scottish silver and gold jewellery, specially used in brooches and buckles combining different colour agate. Black and botswana agate was priced in Victorian jewellery and almost any single colour variety was used during the Art Deco period, from green, black and white to auburn jasper agate. In contemporary jewellery Agate has experienced a huge revival and it is used in almost every costume collection as well as by fine jewellery makers like Kimberly McDonald to masters like JAR.

LUZ CAMINO: First art, then jewellery

It is not every day that a Spanish artist gets to the top of the Art Jewellery world, here is Luz Camino's well deserved homage. After more than two decades making and designing strikingly unusual pieces of jewellery or little bejewelled sculptures, Madrid based Luz Camino is currently featured in the recently published book  "21st Century Jewellery Designers", retailed at Bergdorf Goodman in New York and exhibited in  the Museum of Arts and Design in New York and the Victoria and Albert Museum in London. Yet in Spain she is a connoisseur's secret, her work is admired by artists and coveted by collectors but still unknown to the general public. She is the first Spaniard that has succeeded as an Art Jeweller, hopefully she will have paved the way for younger talent. And perhaps this will mark the beginning of Art Jewellery being truly appreciated in Spain.

The must have 40 books about JEWELS

Collecting (JAR) Jewels

Ever since my visit to the JAR Exhibition at the Metropolitan Museum in NY a few days ago, I have been circling around the idea of what can I possibly write about it that has not been said or written yet. I came out of the Museum absolutely intoxicated, these were no jewels, they were sculptures set with fabulous gemstones. These may not be pieces for one to wear but most certainly they are pieces to dream about. It did not even bother me that I could not try them on or that none was explaining me the intricacies of the pieces, I just wanted to see them,  their shapes and motifs are so imaginative and surprising that even the idea of them is interesting!. So I have become a hunter for JAR jewellery, and I have decided to start collecting the pictures of as many as I can find.

Crazy about Suzanne BELPERRON

Today Sotheby's London has auctioned a few jewellery pieces that belonged to the Duchess of Windsor. As far as provenance it does not get better than that. And as far as makers, as one should expect with the Windsors, most of the pieces were by Cartier. There was one exception, however, a relatively worthless ring set with a beautiful heart shaped citrine of an intense orange hue. The ring was made (never signed, for she never signed her pieces) by Suzanne Belperron. The estimate was £2,000 to £3,000, surely the less important piece of the series, yet it has been sold, after a fierce bidding, at more than ten times the lower estimate (including premium, but still…). The previous memorabilia articles have all gone for the lower estimate or within the range and the three important Cartier pieces afterwards have been sold at a high price but nothing spectacular. The highlight today has been the insignificant ring made by a remarkable woman jeweller whose creations are becoming collectors' icons.

BVLGARI: blue or green? Christie's or Sotheby's?

Here is an idea for a trip aimed to put together a striking set that surely was never meant to be. This week two pieces made by Bvlgari will be auctioned; the first one by Christies in New York, is a pair of drop earrings that combine sapphires and emeralds in a alternate design. Very Bvlgari, in a JAR kind of way… The Christies auction will take place on December 10th.

The second piece is a 1970's watch made by Piaget for Bvlgari (here is the connection!) and it features the signature snake design of the House set in yellow gold enamelled in vivid translucent blue and green enamel. The eyes are set with two pear shaped diamonds. The watch will be auctioned by Sotheby's in London on December 12th.

A rare Diamond "Escargot" brooch by Suzanne BELPERRON

Suzanne Belperron is undoubtedly one of the grandest feminine figures of all times in the jewellery world. The brand and the archives were acquired by Verdura in 1999, now owned by the Landrigan family, who is now promoting and exhibiting her work. This together with the huge attraction of her pieces in recent auctions have revived her genius and turned her into a cult jewellery designer.

Not unlike Verdura, Suzanne Belperron is better known for her attention to design rather than to precious stones. In fact she often did not even use precious materials, yet her pieces are always perfectly finished and flattering, reflecting her deep understanding of jewellery making.

Her "white" jewellery is quite rare, for she preferred working with yellow gold and coloured stones. The brooch below is therefore a high collectable piece, it was made between 1932 and 1940 and it is set in white gold (not platinum probably due to its scarcity during World War II) with old mine european circular cut diamonds arranged in four interlacing scrolls trimmed with a string of baguette cut  tones. A striking piece, which still carries her "trademark" round voluminous design. The brooch will be auctioned by Christie's NY next week on Dec 11th.

CARTIER Jewels from the Duchess of Windsor

I am going to be vey cheesy, so I apologise in advance. Those who normally read me know that I stick to factual descriptions of jewellery but today was too good to resist. The combination includes lunch at Cipriani (C London now) sitting next to Mr Cipriani himself,  and afterwards trying on the Duchess of Windsor pieces at Sotheby's with no other than Valentino…, yes Valentino!, luckily he was more attracted by the cigarette cases and Duke's memorabilia than the Duchess pieces, so I still have a chance!.

Cartier Amethyst, Turquoise and diamond bracelet from the Duchess of Windsor
The bracelet above is a striking piece, it features a very original combination that was a favourite of the Duchess, amethysts and turquoise. It was made by Cartier in 1954. When the full collection of the Windsor jewels was auctioned for the first time, in 1987, there were five pieces with the same gemstone combination; the best known one being the famous Cartier bib necklace later acquired by Elizabeth Taylor and exhibited in The Art of Cartier. The bracelet matches a ring of similar design made by Cartier in 1989.

There is another piece of great historical significance in the collection, the sapphire bracelet that the Duchess wore in 1972 she was finally received by Queen Elizabeth II.

The auction will take place at Sotheby's London on Thursday, December 11th.

A victorian SAPPHIRE of substance

This week, Bonhams London auctioned forty pieces from the collection of famous best seller writer Barbara Taylor Bradford, best known for her novel "A Woman of Substance" which, with 32 million copies, is one of the top ten bestselling fiction books of all time. The collection was mainly contemporary very large pieces, with only one antique brooch that immediately caught my eye. It was a 44 carat Sri Lankan sapphire with a double diamond cluster all set in silver and yellow gold. The brooch is beautiful and very finely made, and since I have a weakness for victorian cluster brooches, it was destined to make it to the blog. The brooch was purchased by her husband at London antique dealer SJ Phillips in 1996.

Victorian Sapphire Brooch from Barbara Taylor Bradford 

The name Sapphire has a greek origin and it means "blue stone". Together with Rubies and Emeralds, Sapphires are one of the three kinds of most precious stones and the four C diamond quality classification applies to them. So Clarity, Cut, Colour and Carat determine the value of a stone. Although they can be found in a large variety of colours, blue is the most sought after and valuable one.        Origin matters a lot, it signals the stone colour quality (and distance purple hues) but also its rarity. The most sought after ones are from Kashmir because of the purity of their blue and also because since 1937 most mining activity has ceased in the region. The second category in terms of origin, is Burma; the stones from this region display an often referred to as "electric blue" colour due to both its intensity as well as its even distribution. The third most important region is Sri Lanka, the stones here are a bit lighter, yet often more uneven. The light tone brings in more brilliance and this makes Sri Lankan sapphires a favourite stone in jewellery making.

CHANTECLER and his holiday jewels

Chantecler was founded in 1947 on the beautiful island of Capri by Pietro Capuano and Salvatore Aprea. Capri i the 1950s was a magnet for the international jet set and glamorous personalities such as Jacqueline Onassis, Ingrid Bergman, Grace Kelly, Audrey Hepburn and Greta Garbo. All of them were frequent visitors who soon became collectors of the colourful and exuberant jewels created by Chantecler's charismatic founders. Today, Chantecler is a prestigious brand run by the Aprea family, still designing jewels that embody the "pure spirit of Capri".
Chantecler diamond and sapphire earrings
The pair of earrings above represents it to perfection, a cascade of marquise cut diamonds and sapphires, set in a symmetrical design, one in diamonds with a sapphire cluster, the other one with sapphires in a diamond pave setting. Elegant yet daring, a bit of a rebel act in a holiday mood… They will be auctioned by Bonhams in London on Dec 5th.

An adorable pearl and diamond brooch by Buccellati

Not all the fine jewels have a multimillion price tag. After a week of so many record prices and huge diamonds I found this brooch was exactly what I needed: beautifully crafted by Buccellati, it is set with pearls and small diamonds in blackened gold. It is a cute and tasteful piece that will be auctioned by Christie's Hong Kong in the upcoming Magnificent jewels sale, yet this lot comes with no reserve at an estimate below $2,000!.

One to watch! JAR Chalcedony and kunzite ring

Tomorrow's Sotheby's Geneva Magnificent Jewels auction will be one of the most important events of the year for many many reasons. The pink star amongst them. However, there will also be other "minor" treasures that are worthwhile to watch, in the unlikely event that they go unnoticed to main the collectors and dealers.

The ring below, signed by JAR, is one of them. Made out of Chalcedony and set with a circular kunzite and diamonds, is almost elfish!

Art Deco Jabot pins, amongst most versatile pieces of jewellery

Cartier, Art Deco Onix and diamond jabot pin
Art Deco Onix and Diamond Jabot pins

The brooch above was made by Cartier in the 1920's and it is set in a typical combination of black onix and diamonds on platinum. The design is very unusual with the top end featuring a long fringe or tassel with cascading large rose cut diamonds. It is part of the upcoming Hong Kong Christie's auction on November 26th.
At the risk of turning it into a bit of an obsession, I find Art Deco monocrome combination fascinating!.

Art Deco Onix and diamond Jabot Pin at Macklowe Gallery, NY

Jabot pins are a particular type of brooch. Their main characteristic is that they are usually made out of one large pin which has adornments on both ends, the lower one normally being detachable so that it can be fastened. This way, when the brooch is worn on a garment, the pin is invisible leaving the two ornaments as if floating. Jabot pins get their name from a ruffle used by men and women to decorate shirts on the front and dates back to the seventeenth century. The pins became a piece of jewellery in the Art Deco period, since their elongated geometric shape (and symmetry in many occasions) suited the style to perfection. They were worn as brooches in multiple ways and even on hats and handbags. The variety of Art Deco designs for this type of brooches in inmense, and they are undoubtedly one of the most versatile pieces of jewellery.

Rarely worn today, these pieces are a collection's theme on their own. Like necessaire cases and minaudieres, each surviving original piece is unique and worth to be treasured.

CARTIER 1920's Rock Crystal Vanity Case

Cartier, 1920's vanity case

This is a great collector piece, a vanity case made by Cartier in the 1920's. It is exceptional for its beauty but also for its rarity and original design. A black enamel box adorned with a reverse intaglio carved crystal, set with rose cut diamonds and suspended of a rock crystal ring with a black silk fringe adornment. It cannot get more Art Deco than this. The box opens to reveal a mirror and two powder compartments.

I became fascinated with vanity cases this past summer after I visited the Goldsmith's Hall exhibition in London. These boxes represent the ultimate luxury and adornment to me, bejewelled and exquisitely made., they are exquisite and the highest representation of refinement and sophistication, for who would think of having make up custom made nowadays?...let alone fit it is a precious stone golden box...
 The lot is part of Sotheby's magnificent jewels auction in Geneva on November 13th

An Art Nouveau Rene LALIQUE bash at the next auction by Christie's King Street in London

Rene Lalique Art Nouveau corsage ornament

Normally one piece made by Rene Lalique in the purest Art Nouveau style would already be the highlight of any auction. This month we have six of them, all of them offered at the same time by Christie's in London. I cannot think of a better opportunity to start an Art Nouveau collection!.

Glass and Opal Art Nouveau pendant by Rene Lalique

Gold and horn leaf brooch by Rene Lalique

When Rene Lalique presented seventeen pieces and four drawings in 1985 at the Salon des Artistes in Paris the jewellery world went upside down. Not only was a pioneer and created the Art Nouveau style, he was a true rebel and questioned all the basic principles that had grounded jewellery for centuries: A piece should be valued for the artistry of its design and its colour harmony more than for the price of the precious metals and stones it displayed. And he went further, to prove it, his designs used all kind of affordable semi precious stones, enamel and unconventional materials like ivory or tortoiseshell. At the Paris Exposition Universelle in 1900 he was already revered as a Modernist genius and the style had rapidly expanded across Europe and the US. By 1905 the Art Nouveau movement had disappeared; it died of its own success, the "cheapness" of the materials attracted many craftsmen, artists and jewellers that could not have afforded entering the trade otherwise, they were driven by an unprecedented demand also caused by the prices. Thus, a huge number of replicas and uninteresting cheap versions of Lalique's work flooded the market and the style was then dismissed by the elite.

Only Lalique's creations and those a few others like George Fouquet, Gaillard, Henry Vever Wolfers or Louis Comfort Tiffany have survived as true masterpieces.

A rare Spanish Art Deco Sautoir by LUIS SANZ

It is not very often that one comes across a very important piece of jewellery that has been made in Spain during the past century. One could argue that with a civil war between the two World Wars and decades of international embargo, the country was not economically buoyant. But the few pieces that do come out in the London or Geneva auctions are truly splendid.  The sautoir below features three magnificent sapphires and it was made in the 1920's by Luis Sanz. Luis was one of the two sons of Sanz Joyeros, a jewellery dealer in Madrid at the beginning of the Twentieth Century; in 1918, the two brothers went separate ways, Juan kept the dealing business and Luis opened a high end establishment. He soon became purveyor to the Crown and made a famous short necklace for Queen Victoria Eugenia with seven of the Colombian emeralds that belonged to Eugenia de Montijo.

The piece will be auctioned by Christie's London on November 13th.

An Egyptian crown jewel: the emerald Art Deco necklace by Van Cleef and Arpels

Everyone knows that a truly fine jewel is as beautiful on the reverse as on the front. To be worthy of the title, great pieces also need to be "finnished" and this means no sparing of gemstones or motifs even if they might not be seen. Designs have to be consistent across the whole jewel, like in couture, this feature distinguishes "haute joaillerie" from the rest.
Art Deco emerald necklace by Van Cleef and Arpels

The necklace above is exceptional on all accounts; Provenance goes back to HRH Princess Faiza of Egyp, Maker is Van Cleef an Arpels, gemstones are ten magnificent colombian emeralds and Period: Art Deco. Yet, the most striking thing about it is the design. The intricate fringe on the front with nine emerald beads dropping from a sophisticate diamond link design and the pendant clasp at the back with a similar motif and another drop emerald. It was made by Van Cleef and Arpels on 1929 and altered in 1937. The piece was sold in 1947 to Princess Faiza of Egypt. It will be auctioned by Christie's in Geneva on November 12th.

Princess Faiza was one of the five daughters of King Fouad I of Egypt (1968-1936) and the sister of the last king of Egypt, King Farouk, dethroned in 1952 by a military coup, which forced the entire family to go in exile. 

"Born at Abdine Palace on November the 8th of 1923, Princess Faiza was the most attractive of King Farouk's five sisters. In 1945, she decided to marry a distant Turkish cousin, Mohamed Ali Bulent Raouf. It is often said that King Farouk was not very pleased by this wedding as he would have much preferred his sister to marry a foreign prince. Princess Faiza was very lively, witty, and she had a wonderful taste for clothes and jewels. She was a regular customer of the Parisian couture houses, especially Chanel. As far as jewellery was concerned, Van Cleef & Arpels was definitely her favorite house.

One of the most famous jewels ever made by Van Cleef & Arpels is the double 'Clip Pivoine', two peonies flowers, set in the famous 'Serti Mysterieux' for which Van Cleef & Arpels is so famous, are joined together with diamond leaves. The craftsmanship of that piece is so unique that it seems the petals would move if you blow on them. That double clip was also part of Princess Faiza's collection. She sold the two brooches separately a few years before she died in 1994. Fortunately one of them now belongs to the Van Cleef & Arpels antique jewellery collection. The fate of the second flower remains a mystery. 

The emerald and diamond necklace which is offered here demonstrates the same taste. The craftsmanship is perfect. The emerald drops hang from the diamond motives set in a very pure Art Deco style. The necklace is imposing, which is normal as it was worn by Princess Faiza as a 'Court Jewel', yet it is very graceful and the stones move very gently on the 'décolleté' of the woman who wears the piece."
