The Cora Sun Drop Diamond was certified as a "fancy vivid yellow," the rarest and most desirable color for a yellow diamond. The 110.3 carat stone, which was discovered in South Africa in 2010, had a pre-sale estimate of $11-15 million. It was cut, polished, and put up for auction by New York-based, Cora International. The price, inclusive of commission and taxes, sets a world record for a yellow diamond and was the top lot at Sothebys semi-annual jewellery sale. In our Sun Drop Collection featuring our signature Diamondeau? - flawless simulated diamond; we are not going to ask the same price point for a single stone.
