One of the diamonds was a 7.1 carat cushion cut vivid yellow diamond which sold for $52,000 per carat. Another was a 2.3 carat cushion cut vivid yellow diamond which sold for $19,000 per carat.
The tender of the Ellendale goods follow recent trials on a selection of its white diamonds from the Letšeng Mine, known for their high quality and top prices. They, too, were cut and polished before they were sold.
According to Clifford Elphick, CEO of Gem Diamonds, “significant additional margin” can be made from selling their goods polished. “We are very encouraged by the results,” he added.
