Narrow the possibilities for a gemstone by comparing its thermal response with the tester’s indicated groups.
Features and specifications
- Thermal-conductivity gemstone screening.
- Analog indication across gemstone groups.
- Built-in calibration support.
Who it suits
A bench option for experienced jewelry hobbyists who understand that several materials can share similar thermal behavior. Use the readings alongside other appropriate identification methods.
Before you choose
PGT II does not separate diamond from moissanite or prove that a stone is natural rather than laboratory-grown. Similar responses can overlap, and testing conditions matter. Obtain a qualified identification for valuable or uncertain stones.
