25.5 Carat Blue Diamond Found in South Africa



It’s only fitting on a day a 34.65 ct. pink diamond sells for $39.3 million that we also feature an equally impressive big blue diamond.

A 25.5 ct. blue diamond was recovered by Petra Diamonds Limited at the Cullinan mine in South Africa.

This isn’t the first blue stone the company has unearthed. In 2009, it found a 26.6 ct. rough that would become the 7 ct. Star of Josephine diamond that sold for more than $9 million at Sotheby’s. Petra Diamonds also set a record in December 2011 when it sold a 4.8 ct. piece of blue rough from the same mine for $1.45 million—more than $300,000 per carat.
