Diamond (Cubic)
Thumbnail, 1.1 x 1.1 x 1.0 cm, 18.75 ct
South Africa

A choice, textbook diamond cube of large size, weighing in at a hefty 18.75 carats. The crystal has edges that range from 1.0 to 1.1 cm. When even minimally backlit, there is a nice translucency and color, and it exhibits the textbook adamantine luster of the native diamond crystal described but seldom seen. Complete all around!
