Natural black diamonds are very rare, and often have a fairly poor color and clarity, with gray stains and scratches on the surface. This is the reason why heated black diamonds have become common and popular on the market. Heated black diamonds are natural diamonds, whose color has been improved by a heating process in a vacuum.

The benefit of heated black diamonds is that they are much more reasonably priced than entirely natural black diamonds, and also that it is possible to get a beautiful stone with a good clarity and color.

Clarity is much more important for black diamonds than for other natural color diamonds. They are the only non-transparent diamonds, and their appearance is like that of a mirror. Consequently, the smallest scratch or other impurity on the surface will be very clearly visible in a black diamond.

We are here to advise you on what black diamond to choose, depending on the purpose of your purchase.
