When a Diamond craftsman examines the rough stone, he imagines what shape the Diamond will take. He pictures the Diamond after considering the shape of the rough stone, the size, inclusions and how much weight will be lost in the process of cutting. The most popular shape of a Diamond is the one in an engagement ring, having a round brilliant cut. It is usually cut from an eight sided crystal. The marquise, oval, pear, emerald and heart shaped Diamonds are known as fancy cuts. These are fashioned from different shapes of rough Diamonds that cannot be crafted into a round brilliant cut. With the exception of the heart-shaped cut, cuts can have as many as 58 facets. The shapes of facets differ in each of the cuts. The tiny polished planes on the surface of each Diamond accounts for the brilliance & fire of Diamonds. The precision & skill of the craftsman cutting the stone determines the quality of the cut, the extent of brilliance & the allure of the Diamonds fire.
