The listing, Unset Blue Diamond has ended.
My husband's grandmother gave this blue diamond along with it's twin, which my husband had set in my engagement ring. Both diamonds were verified to be real and genuine by Crown Diamonds, but they have been color treated. It does have a slight chip in the top but it is not too noticeable and still quite beautiful. I do not know the karat or weight, i'm sorry. Would look lovely in a necklace or ring. I'm sorry for the picture quality, I had to do the pictures with the flash on to get a good image of it, the diamond is actually a darker blue than shown but when light hits it, it shows this color.
