Five Extremely Rare Blue Diamonds Unearthed at Cullinan Mine
Petra Diamonds has announced the recovery of five Type IIb blue diamonds of high quality at its Cullinan mine in South Africa.
According to a press release, the diamonds “are also significant in terms of their size, being 25.75, 21.25, 17.57, 11.42 and 9.61 carats, and are assessed to be individual stones and not originally part of one larger diamond”.
Blue diamonds are rare enough, and the last blue diamond of any significance was recovered a year ago at Cullinan. The miner said that “it is therefore even more unusual to recover five high quality stones around the same time, all in the space of one week’s production”. Petra added that given the challenges presented by the COVID-19 pandemic, it is “maintaining a flexible approach to sales” and “is therefore still evaluating the optimal route to market for the stones”.
