Diamond bracelet that doubles as a tiara is highlight of Adam’s Fine Jewellery sale

An important art deco diamond bracelet, designed by Austrian artist Erwin Lang, is a highlight of Adam’s Fine Jewellery and Watches sale, which will take place in a live online auction on Tuesday September 12th.

Lang was the half-brother of Erich Köchert of Austrian imperial jewellery house Köchert, which is now run by the seventh generation of the original Köchert family.

In 1831, the house was commissioned for the first time by Emperor Franz Joseph I, to create a gold box, which was to be gifted to a Turkish diplomat. So began a long and important relationship with the jewellery house and the imperial House of Austria, who noted that the company had “the highest reputation for honesty, for the excellence and good taste which distinguishes their workmanship, and both are known to carry out commissions to the satisfaction of high nobility”.

With 38 carats of brilliant and baguette cut diamonds, the bracelet is illustrated in the book Köchert, Imperial Jewellers in Vienna, Jewellery Design, 1810-1940, by Irmgard Hauser-Köchert.

The stunning piece was then later redesigned as a tiara and sold by Bulgari in Rome in the 1950s and is accompanied by a certificate from Amanda Triossi, a specialist and author on Italian fine jewellers Bulgari and former curator of the Bulgari Heritage Collection, stating that the tiara was sold by Bulgari in the 1950s.

Demand for tiaras, which take their name from high-peaked headdresses of ancient Persian royalty, has risen in recent times. In the postwar eras of the 20th century, demand for formal attire receded – as they were then limited to royal receptions – making them rare enough symbols of the extravagance of former times. Today, they are popular with Asian markets, with a third of tiaras recently sold through Sotheby’s going to Asian buyers. Purchased as bridal headpieces, creating a family heirloom to be passed down to further generations, some are also becoming popular on international catwalk shows and events such as the Met Gala. A recent feature in Harper’s Bazaar suggested that the fantastical Regency-era drama Bridgerton had prompted a spike in interest in the statement pieces, with one London-based jeweller, Susannah Lovis, reporting a 300 per cent rise in searches for tiaras following the Netflix show’s second season.

The bejewelled piece in Adam’s sale, which is the property of a titled European woman and expected to achieve between €50,000 and €70,000, works as both a bracelet and headpiece – with an additional section with 4.50 carats of diamonds in a band to make the piece operate as a tiara.

A really beautiful art deco emerald and diamond bracelet from circa 1935 (lot 37, €25,000-€35,000) also features. With a continuous line of rectangular cut emeralds in the centre, shouldered by old European cut diamonds and mounted in gold and platinum, it has approximately 25 carats of diamonds.
