[QUOTE="Lefty, post: 413170, member: 2976"] Actually, itdid play up a bit when it came to polishing. It seems to have a tendency to pit and orange peel similar to sapphire. Ive since read that it should be pre-polished with loose #8000 grit beforethe final polish in ordertk overcome this. I polished it with #100 000 diamond on ceramic and it really only biggest facets that gave anytrouble. There are so many facets on the 12mm wide gem that they are mostly really smalll and I think small facets tend to overcome this problem easier. I havent tried nanositol, the only other man made I have cut is cristinite. Its a lot of fun to play with, especially the bi-coloured stuff. Good to hear that somebody else likes black stones! A brilliantly polished black stone can ,ook stunning! [/QUOTE]
