The first desktop instrument that estimates colored gemstones and identifies diamonds, using the principle of thermal properties of gemstones. Presidium Gemstone Tester / Colored Stone Estimator is the only colored gemstone thermal tester in the industry. It provides a quick and easy way to identify diamonds and separate common colored gemstones from one another based on their thermal conductivity. Coated gemstones can also be generally tested with the PGT/CSE. The Presidium Gem Tester / Colored Stone Estimator has a retractable probe tip that ensures consistent pressure against the gemstone during testing for more reliable results. With the industrys thinnest probe tip size of 0.6mm, PGT/CSE tests diamonds as small as 0.02ct. NOTE: Does not differentiate between natural and synthetic colored gemstones.
