BlueRock Diamonds PLC (LON:BRD) said it has sold 2,900 carats at an average price of US$300 per carat.
The aggregate consideration amounted to just over US$870,000.
The production comes from the company’s Kareevlei diamond mine in the Kimberley region of South Africa.
"This is the third successful private sale conducted through an agent in South Africa at a price, which we consider competitive in the current market, demonstrating the consistent strong demand for our high-quality diamonds from long-standing customers,” said BlueRock’s executive chairman Mike Houston in a statement.
"We will continue to update the market with upcoming sales both through private sales in South Africa and also our previously announced plan to export directly which remains a key objective for Bluerock."
