Presidium Dial Gauge measures from 0.0 to 23.0mm in 0.1mm divisions. The PDG features an easy-to-read millimeter and carat scale, and is only dial gauge in the industry that combines dual measurements for gemstones in millimeters with corresponding carat conversion for round brilliant-cut gemstones...
Presidium Duo Tester II (PDT II) is the only comprehensive tool on the market that combines two proven testing methods for gemstones. PDT II differentiates diamonds from its simulants based on both their thermal conductivity and reflective indexes. Coated gemstones can also be generally tested with ..
The Presidium Moissanite Tester II (PMT II) measures the electrical conductivity of the gemstones directly, determining if the gemstone is a genuine diamond or a moissanite (a diamond simulant).
Presidium recommends the use of the Presidium Moissanite Tester II after a positive test result for di..
Presidium Electronic Gemstone Gauge is the industry’s first digital gemstone gauge and remains the only reliable one able to convert gemstone dimensions to estimated carat weight for round brilliant-cuts.
Utilizing solid-state electronics to accurately measure up to 1/100mm, this gauge also featu..
The Presidium Gem Indicator, the only handheld tester in the industry specifically for colored gemstones, indicates up to 31 different types of colored gems based on their thermal conductivity and even features a color input function that allows users to select from a range of 12 common colors, ther..
The Presidium Mulit Tester III has been developed to distinguish between diamonds and moissanite using the combined principles of Thermal and Electrical Conductivity. The measuring probe, with its electronic circuitries is designed to detect and segregate data collected from the gemstones via a cust..
