The Presidium PGI portable gem indicator is specially designed for testing coloured gemstones. The thermal testing device consists of two connected thermometers: one is electronically heated, while the other is heated by the gemstone under test. The difference generates an electrical output that is then amplified and displayed on the LED display.
