Lesotho focused miner Namakwa Diamonds will sell a 29.59 carat, fancy pink rough stone in Antwerp this fall. The company discovered the diamond at its KAO mine in the African country on June 12, according to brokerage firm Bonas Couzyn, which will facilitate the sale. The stone named the Rose of KAO will appear in Antwerp for viewings from September 17 to 28, and bidding in an online tender will close October 1. The auction is part of the fourth sale of KAO goods this year. Namakwa owns and operates the KAO mine through its subsidiary, Storm Mountain Diamonds. The asset has a record of producing fancy color diamonds. The miner recovered the 36.06 carat Pink Storm in December 2013, and sold it the following month. Source: Diamonds.net
