A brilliant is a diamond or other gemstone, cut in a particular form with numerous facets so as to have especial brilliancy. The shape resembles that of a cone and is meant to maximize light return through the top of the diamond. Even with modern techniques, the cutting and polishing of a diamond crystal always results in a dramatic loss of weight; rarely is it less than 50%. The round brilliant cut is preferred when the crystal is an octahedron, as often two stones may be cut from one such...
A brilliant is a diamond or other gemstone, cut in a particular form with numerous facets so as to have especial brilliancy. The shape resembles that of a cone and is meant to maximize light return through the top of the diamond.
