Although no refining is necessary, cutting & polishing is. Sorting & grading of the raw stones is done before they leave for the Antwerp dealers in the SL government's Freetown diamond exchange office. This office also certifies that the diamonds are conflict free in accordance with the Kimberly process. According to John, we lose up to a full half of the caret size of the raw stone during cutting & polishing. When you are talking about the size of the stones we are dredging up that amounts to significant loss. However, since we are now operating in an newer concession area, known for more colored stones (i.e.canary yellow ones) John stated they would be more valuable. At this point, IMHO, the company has done the fiscally prudent thing. It is concentrating on gold production. The couple hundred dollars each raw stone brings us is just the icing on the cake.
