Presidium Gem Indicator

Presidium Gem Indicator for colored gemstones

For a proper use: to be used by qualified personnel (with gemmological expertise/knowledge)!

All-New Digital Gemstone Tester that tests up to 31 types of colored gemstones

A revolutionary handheld tester developped specifically for colored gemstones.

It 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, thereby achieving more accurate results. With an easy-to-read clear digital LED screen, this smart thermal tester also comes with the Presidium patented refined probe tip.

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
