The stone was recovered from the Saxendrift Extension property is white and has a tint, but its color and shape are wholly compatible with cutting and polishing for commercial value and one of the largest stones produced in the Middle Orange in recent times. It is the fifth large stone from the resource in three months and second stone discovered exceeding 200 carats in size produced by Rockwell in its eight-year history. The diamond will be sold into the company's beneficiation joint venture with Steinmetz Diamonds at market value, with Rockwell participating equally in the value uplift once it has been polished and sold.
