Colored diamonds continue to be hot sellers, if recent results from miner Petra Diamonds are any indication.
At its recent tender in early December, the company sold a 4.8-ct. piece of blue rough produced at the Cullinan mine in South Africa for $1.45 million, or more than $300,000 a carat.
Petra says that it is the highest per carat price it has ever achieved for a piece of rough. In addition, the miner says it is confident that the price is “one of the highest values per carat ever achieved on the sale of a rough diamond by any rough diamond producer,” according to a statement.
“Cullinan is renowned as the world’s only reliable source of blue diamonds and this sale demonstrates how rare and desirable they are to the international market,” the statement added.
