[Rockhounds] Spectroscopic gemstone screener rapidly identifies natural and synthetic diamonds.

[Paul]

Spectroscopic gemstone screener rapidly identifies natural and
synthetic diamonds. A UV-fluorescence spectroscopy-based
instrument with a handheld probe identifies various types of
diamonds, as well as diamond fakes such as corundum, spinel,
and beryl. John Wallace, Laser Focus World, July 21, 2021
