Pen to gauge screening and separation of synthetic diamonds

A Hong Kong-based firm, Diamond Services Ltd, is to release a low-cost and highly accurate device for the screening and separation of synthetic diamonds from natural diamonds. The device, a pen-shaped pointer called the DiamaPen will be introduced at this month's Hong Kong Gem & Jewellery Fair. It will be offered to diamond traders who need an affordable and reliable tool to detect and separate synthetic diamonds, both HPHT and CVD grown diamonds, from their natural counterparts.

J. Kuzi, owner and CEO of EGL Aisa said "The detection of fancy yellow synthetics is the easiest and fastest job for the DiamaPen. The procedure takes a bit longer for colorless CVD synthetics, but in all cases the testing results are consistent and highly satisfactory. While this new device is not a replacement for a full-scale identification run in a gemological laboratory, it is and will be an important tool for those working in the diamond industry and trade," Kuzi concluded.

The DiamaPen employs the 405 nm wavelength for the operation of its laser beam. J. Kuzi, who tested the DiamaPen, said that due to the high-power output of the laser beam, anyone handling the laser pen will need to wear special safety glasses.
