Yellow Diamond Ring to Lead Bonhams Sale

A 10.19-carat yellow diamond ring will lead an upcoming auction at Bonhams in London, where it is set to fetch up to GBP 160,000 (approximately $199,300).

Bonhams will offer the radiant-cut, fancy-intense-yellow, VS1-clarity stone, set between shield-cut diamond shoulders, at its December 7 London Jewels auction, it said Tuesday.

Two additional yellow diamonds for sale include a brilliant-cut, 10.02-carat, fancy-yellow diamond single-stone ring and a step-cut, 8.45-carat, fancy-yellow diamond ring accented by four pear-shaped diamonds set between baguette and step-cut diamond shoulders. Both pieces carry estimates of GBP 50,000 to GBP 70,000 (approximately $62,300 to $87,200).

The 149-lot auction will also feature pieces from multiple single-owner private collections, spanning from 1870 to the modern day. These comprise jewels from Cartier, Bulgari, Graff, Moussaieff, Van Cleef & Arpels, Harry Winston, Boucheron, Tiffany & Co., David Webb, and Grima.

Highlights from a single-owner private European collection are a Lalique Art Nouveau enamel, pâte-de-verre, sapphire and diamond pendant from around 1905 to 1915; a Cartier Panthère coral, emerald, onyx and diamond brooch, circa 1968; and a Cartier ruby and diamond clip and ear clip suite brooch combination that dates to about 1960.

Another collection, from a descendant of Dorothy Maud, Countess Haig, boasts a pearl and diamond tiara necklace presented to the countess by Queen Alexandra in 1905 on her marriage to General Haig.
