This is Lithium Tantalate, a very exotic crystal used in industry but rarely used as a gemstone. Uses include everything from fiber optic networks to fusion reactors, and in the past was occasionally used as a diamond substitute. Crazy high dispersion and refractive index. Impossible to capture on accurately on camera, be assured they look even better in person.
