Rough diamonds
Laboratory-grown (synthetic) HPHT single-crystal rough diamonds produced by New Diamond Technology are the largest in the world and characterized by a high crystal-clear perfection, stable quality and low level of uncontrollable impurities. The cubic-octahedron shape of a diamond is specific for HPHT method, but the company has a technology which allows to control and manage diamonds morphology to optimize yield ratio.
Generally we grow crystals of two types: colorless (IIa) and blue (IIb). The unique technology allows to produce rough diamonds more than 50 ct in size, what can't be achieved by competitors for the moment.
Commercially available are sizes from 8-10 GR and up to 10.0 сt.
