As diamond traders continue to express concerns over undisclosed lab-made diamonds, a Hong Kong firm is offering a low cost way to identify them. Their solution is a $200 laser pen.
The device, a pen-shaped pointer called the DiamaPen will be introduced at this month's Hong Kong Gem & Jewellery Fair by Diamond Services Ltd.
The company says the device is highly accurate and can identify HPHT and CVD grown diamonds.
The DiamaPen uses the 405 nm wavelength for the operation of its laser beam.
Joseph Kuzi, owner and CEO of EGL Asia who tested the DiamaPen, 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."
He added that because of the high-power output of the laser beam, anyone handling the laser pen would need to wear safety glasses.
