When a diamond is dark grey or truly black it is referred to in the trade as a black diamond. Such a diamond may be opaque to nearly semitransparent. "Carbonado" is a particularly tough industrial variety of diamond because of its multi grain structure.

Laboratory grown black diamonds are man made diamond, not a synthetic or simulant. 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.

Laboratory Grown Black Diamond

Thomas Michaels Designers are suppliers of these remarkable new laboratory grown diamonds. They are not a simulant or a synthetic, but are genuine diamond, grown in the laboratory. We have set these unusual diamonds in some wonderful pieces in platinum and white gold that we have designed . Their unconventionality makes them fun to design around. Our master diamond cutter cuts these diamonds to our requirements. We have the ability to supply to you any diamond cut or shape including sizes from .25ct up to 5.00ct and sometimes larger. 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 not unlike 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.

We offer to our clients these remarkable stones at just a fraction of the price of natural black diamonds. Contact us for specific information pertaining to your size and shape requirements.

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.
