The 43.59ct radiant-cut fancy intense yellow diamond ring is included at Fellows’ Antique & Modern Jewellery sale on December 7. It is accompanied by a report from the GIA and a Graff Certificate of quality.
“Yellow diamonds are synonymous with Graff,” says Fellows managing director Stephen Whittaker, who added that the ring is of “superb, excellent quality”.
It is estimated at £900,000-1.4m. If it reaches its top level it would mean a house record for the auctioneer. The current record stands at £131,000, plus buyer’s premium, for a platinum diamond single-stone ring which it sold in 2013.
The current auction record for any yellow diamond is held by the 100.09ct Graff Vivid Yellow, which sold for CHF14.5m ($12.4m) at Sotheby’s Geneva in May 2014.
