What are clarity enhanced diamonds?

Clarity enhanced diamonds are natural diamonds which undergo a treatment process to artificially improve clarity in the diamond.

The treatment process typically falls into two main processes. Firstly laser drilling and secondly fracture filling. Both treatments aim to reduce the appearance of natural clarity characteristics within a diamond.

Laser drilled diamonds

Laser treatments involve drilling a fine laser hole through a diamond. This process burns away an internal inclusion. The laser hole allows access to bleach deep inclusions. As a result, the diamond benefits from enhanced clarity and an improved appearance. The image below, courtesy of the Gemological Institute of America shows the drill-hole under high magnification.

Laser holes can be very difficult to see, even with a trained eye. Under 10x magnification, we look for small holes on the surface of a diamond. From these holes, fine hair-like lines extend into the…
