Storm Mountain Diamonds operates the Kao mine, which is located in Lesotho, a small kingdom encircled by South Africa. Storm Mountain is a 62.5 percent owned subsidiary of Namakwa Diamonds, which has other mining operations in South Africa as well as off the coast of Namibia.

Fusion and I. Henning & Co. Ltd. have been in charge of jointly handling the rough diamond tenders for Kao since 2012.

In commenting on this latest tender, Fusion Alternatives CEO David Kuchler said that the Kao is “building a reputation for the recovery of world-class magnificent stones,” including the 36.06-carat, Type IIa “Pink Storm” diamond that sold for $15.36 million at the Fusion/I. Henning tender held in Antwerp in January 2014.
