The De Beers group of companies acquired a 25% stake in Curtis Fitch, which provides services in the field of online auctions.
The diamond giant said that these investments are intended to expand the successful partnership of both companies.
De Beers sells about 10% of the mined diamonds through auctions. The company held its debut online auction with the support of Curtis Fitch in 2008.
"De Beers' leading position in online diamond auctions is based on our ability to understand the needs of our international customers and provide them with opportunities to supply raw materials that always meet their unique and changing needs," said De Beers vice president of auction sales Neil Ventura (Neil Ventura).
