## Description

Presidium Gem Tester II is based on the invention of Professor Julian Goldsmid, University of New South Wales in Australia.

In the second generation, the Presidium Gem Tester II quickly and easily identifies diamonds/moissanite and separates up to 16 common colored gemstones based on thermal conductivity.
