Our industrial grade diamonds are designated for industrial use, principally as a cutting tool or for abrasive drilling. In general, industrial diamonds are too badly flawed, irregularly shaped, poorly coloured, or small to be of value as gems, but they are of vital importance in the modern metalworking and mining industries.We mine our industrial diamonds from natural deposits.  Among our naturally occurring diamonds, we have three varieties: ballas, bort, and carbonado.

Ballas is composed of concentrically arranged, spherical masses of minute diamond crystals. Ballas is extremely hard, tough, and difficult to cleave.

Bort is a gray to black massive diamond, the color of which is caused by inclusions and impurities.  Drilling bort is composed of small, round stones averaging 20 to the carat and is used in diamond drill bits.

Carbonado, known in the trade as carbon, is black opaque diamond. Carbonado has no cleavage and therefore is valuable for use in diamond-set tools.
