Presidium Gem Indicator (PGI) - Handheld Tester

The Presidium Gem Indicator is an enhanced and more convenient handheld version of the revolutionary Presidium Gem Tester/Colored Stone Estimator. It distinguishes between diamonds and other colored gemstones using the principles of thermal conductivity. The Presidium Gem Indicator probe consists of two linked thermometers; one which is heated electronically, while the other is cooled by the gemstone being tested. The difference in temperature creates an electrical output, which is then amplified and displayed on the new digital organic LED display. It is simple to use, easy to maintain and quick in giving you intelligent results about your colored gemstones.
