A private buyer pursued a 100-carat yellow diamond to 14.5 million Swiss francs (16.3 million dollars with buyer's premium and fees) at a Sotheby's jewelry sale in a Geneva that generated 125.5 million francs overall. The "Graff Vivid Yellow" set a world auction record for a yellow diamond and for a Graff diamond, according to Sotheby's.
There were some long moments when the diamond had to be waited on. For fifteen minutes during the evening session of the auction at the Hôtel Beau-Rivage, the bidding was suspended.
“The eventual buyer of the yellow diamond who was in the room got confused, I think, with her calculations of francs and dollars and came back a few minutes later and said could you re-offer it because we still wanted to buy," said David Bennett, chairman of Sotheby’s Jewellery Division in Europe and the Middle East. "It was quite a nice thing to happen.”
