Cartier London created an amazing tiara for Beatrice Countess of Granard in 1937 (illustrated XXX). The three brooches sold as lot 194, are illustrated as being the central part of the tiara (signed Cartier London) as well as two side panels (numbered 2 and 5). It was very common for jewellers to create tiaras or necklaces with detachable pieces, for them to be worn different ways on different occasions. Christie’s is honoured to offer these beautiful Art Deco brooches, rare witnesses of a bygone era.

Further outstanding pieces in the sale include a superb Art Deco diamond Bandeau by Cartier, which can also be worn as a choker, two bracelets and as a brooch (estimate: CHF 300,000-500,000). The bandeau is the most timeless head ornament, having been in fashion during the early 20th century and enjoying a resurgence today. It transcended the Art Nouveau, Belle Époque and into the Art Déco period where the bandeau was the most fashionable accessory. Further examples of transformable jewels from the leading jewellery houses include an iconic diamond ‘zip’ necklace by Van Cleef & Arpels (estimate: CHF170,000-270,000).







Lot 245. Superb Art Deco diamond Bandeau, CartierEstimate CHF 300,000 - CHF 500,000 (USD 300,000 - CHF 500,000)Price realised CHF 1,065,000. © Christie's Images Ltd 2019.

Cushion, old and baguette-cut diamonds, platinum (French marks), detachable for wear as a choker, as two bracelets or as a brooch, circa 1920, bandeau 40.5 cm, choker 34.0 cm, bracelets 17.8 cm, brooch 6.0 cm, brooch signed Cartier Made in France, brooch and bracelets nos. 7071C.

The head ornament called bandeau derives its name from the French word ‘bande’ meaning ‘strip’. Through its simple yet elegant design, it can be worn as a tiara or as a hairband, making it the most timeless of all head ornaments. It really came into fashion at the turn of the century, from the Belle Epoque to the Art Deco period, when the bandeau was the most fashionable thing to wear on a night out in 1925 High Society Paris.
During a short space of time, fashion changed immensely, the voluminous dresses and hairstyles that were still fashionable in the late 19th century had been replaced by short haircuts and exotic dresses that emphasized the body. The simplicity of the bandeau was a perfect match for the modern style of the Art Deco period. In his book Cartier Jewelers Extraordinary, Hans Nadelhoffer referred to bandeau tiaras as ‘an ideal complement to bobbed hairstyles’.
Cartier were experts in creating head ornaments at the turn of the century, they famously created a bandeau tiara for Queen Elizabeth the Queen Mother (illustrated left), that could be transformed into three bracelets. They were also the master craftsmen behind Queen Elisabeth of Belgium’s superb bandeau tiara (illustrated left).
Bandeau tiaras were often made in the fashion of multipurpose jewellery so they could easily be taken apart and turned into bracelets and brooches, just as lot 245 which can be worn as a choker, a brooch, or as a pair of bracelets; making this bandeau a timeless jewel which would suit any connoisseur’s collection.








Lot 175. Diamond ‘zip’ necklace, Van Cleef & Arpels. Estimate CHF 170,000 - CHF 270,000 (USD 170,000 - USD 270,000)Price realised CHF 237,500. © Christie's Images Ltd 2019.

Circular-cut diamonds, platinum and gold (French marks), transformable for wear as a bracelet, necklace 40.5 cm, bracelet 17.3 cm, signed Van Cleef & Arpels, no. ML3781.

Note: One of the most innovative jewels ever created, the Van Cleef & Arpels' Zip necklace is an iconic design. Legend has it that during the 1930s the Duchess of Windsor asked Renée Puissant, the creative director of the brand between 1926-1942, to create a jewelled zip fastener to wear with her evening gowns. Although the patent for the design was registered in 1938, it was not until 1951 that Van Cleef & Arpels presented the first Zip necklace.

The auction will also present an unusual turquoise and diamond Belle Époque brooch, circa 1910, acquired by Dame Nellie Melba at the peak of her career (estimate: CHF 250,000-350,000). In a long list of famous jewellery collectors, Dame Nellie Melba was one of the era's most prominent icons and a well-established client of Cartier. Helen Porter Mitchell, born in 1861 in Melbourne, decided from an early age that she would become a singer. After immigrating to Europe and studying in Paris under Mathilde Marchesi, who suggested that Nellie take the surname ‘Melba’ after her hometown, Dame Nellie Melba became one of the most famous singers of the late Victorian era and the early 20th century. She achieved international recognition as a classical musician and was honoured in the late 19th century by the Savoy Hotel’s French chef Auguste Escoffier with the creation of the Peach Melba .

Highlighting the auction are jewels by renowned jewellery designer Pierre Sterlé, considered to be emblematic of 1950s and 1960s jewellery. In 1934 Sterlé set up his own atelier, in the Place Vendôme, and was considered somewhat of a revolutionary: atypical, audacious and talented, receiving the prestigious De Beers' International Diamond Award three years in a row. Sterlé reinvented the art of manipulating precious metal, setting the gemstones in an elevated fashion reminiscent of the Baroque period; creating a sense of movement in supple and articulated mounts. He created mobile settings which enhanced the scintillation of the stones, varying their colour according to the light. His overruling ambition was to challenge the technical constraints of jewellery design, permitting him to translate the visions from his vivid imagination into jewels. He adored the effect of different colours of gold combined in one object and of varying textured surfaces. Leading pieces from the collection include a beautiful citrine and diamond necklace and ring set, (estimate: CHF40,000-60,000).
