Black Diamonds

When a diamond is dark grey or truly black it is referred to in the trade as a black diamond also known as "carbonado".  Such a diamond may be opaque to nearly semitransparent. The black diamond seems to absorb and reflect light. Most black and grey diamonds are used in industry.  Carbonado is a particularly tough industrial variety of diamond because of its multi grain structure. 

Laboratory grown black diamonds are man made diamond that is grown from a "seed" black diamond.  When cut by a master diamond cutter yields a much more precisely cut stone with higher polish than what is found in "carbonado" natural black diamond. They are genuine diamond, grown in the laboratory. We have set these unusual diamonds in some wonderful pieces we have designed in platinum and white gold. Their unconventionality makes them fun to design around. These opaque jet black diamonds reflect from the cutting on the surface of the stone rather than from brilliance generated from within, creating a unique, attractive look like hematite but with the durability and faceted quality of diamond. Unlike many natural black diamonds that require irradiation to obtain the opaque black color, our laboratory grown black diamonds have not been irradiated.

The lack of grain that occurs in these laboratory grown crystals allows for a precision in diamond cutting and a beauty of surface polish that is not attained when cutting natural black diamond. They are truly beautiful.
