Stellar Diamonds Chief Executive Karl Smithson commented:

"We are delighted with the results from the latest diamond sale from Baoulé via the online auction eDiamond platform. The presence of larger, high value stones and the stability in the rough diamond market has resulted in an average price of US$156 per carat for the latest Baoulé "run of mine" parcel. Stellar's total revenue from diamond sales in 2015 currently stands at US$922,000, of which US$700,000 is derived from Baoulé. Trial mining is on-going and further diamond sales are targeted for the coming year."
