I was really surprised at the quality of the black stone. It appears to be in the neighborhood of an I3 clarity with a good quality cut. The setting is very "stout" and the screw on back works well. The setting itself is finished well and fits the stone appropriately. You can really appreciate this diamond when you get it in the sunlight, It is beautiful. If I could say anything that I would like different in the stone, it may be to have more "girth" than "depth" in the total caret weight. I would recommend this buy to anyone, you can not beat the price.
