In its second generation, the Presidium Gem Tester II provides a quick and easy way to identify diamonds/moissanite and separates up to 16 common colored gemstones based on their thermal conductivity with its clear and direct analog display. A newly redesigned inbuilt calibration reference and adjustment provides ease of operation both indoors and outdoors.
