The Presidium® Gem Tester II (PGT II) provides users with a quick and easy way to identify diamonds/moissanites and separate up to 16 common colored gemstones based on their thermal properties. It can test both polished and unpolished gemstones. The probe tip is the industry’s thinnest at 0.06mm (0.024) for testing colored gemstones as small as 0.02ct. The PGT II was redesigned for the user, and thus has a clear and direct analog display as well as built-in class and calibration discs for reference. Consistent and reliable results every time with no waiting between tests. Replacement pen probe is available - see 8171101. Made in Singapore.
