Jewellery pieces by Tiffany & Co, including those by renowned designer Jean Schlumberger, are among the highlights of an upcoming Bonhams auction in Hong Kong.

The private collection by a Canadian philanthropist, comprising 10 individual pieces, will be sold as part of the auction house’s Jewels and Jadeite scheduled for November 26. Seven of these are jewellery designed by Schlumberger for Tiffany & Co.

Schlumberger, recognised as one of the 20th Century’s most gifted artists, began his career designing buttons and costume jewellery for designer Elsa Schiaparelli in Paris before moving to New York to set up his own salon. 

“The partnership with Tiffany & Co began in 1956, where he went on to create designs that captured the imagination of jewellery lovers. Schlumberger’s designs used gemstones to transform nature into objects of beauty, many of which remain unrivalled in the world of jewellery design,” Bonhams said.

A highlight of the auction is Tiffany & Co’s “Soleste” ring in platinum and 18-karat rose gold adorned with a 10.56 carat round brilliant-cut diamond surrounded by fancy pink and round brilliant-cut diamonds. It has a pre-sale estimate of HK$3.2 million to HK$6.3 million (approximately US$407,654 to US$807,575).

Leading the Schlumberger for Tiffany & Co collection meanwhile is a handcrafted 18-karat gold diamond tulip necklace, designed with an articulated cascade of multi-textured gold tulips with distinctive buds. Interspersed among the tulips are delicate gold bows, scrolls of pave-set diamonds and diamond-set butterflies and dragonflies. The necklace is valued at HK$800,000 to HK$1.5 million (around US$101,912 to US$191,086).
