BLUE PEARLS ROUGH HPHT, to make you save, 1.64 carat, only 1 available. You will have to find a local cutter, where you live. Cutter will cost you about 30-50 bucks (one hour work), in Western World countries. You will lose about 30-40% of weight, when cut. It will all depend of shape you want, and, cutter ability. Still, it is a super-bargain, and, a real jewel. Best cut we would recommend to you, to loose less, would be oval/pear/emerald, and, sometime, round (in the end, it will all depend of the cutter, and stone, bought). Upon request, I can get you larger sizes, always underpriced, and, unique in its type
