How It Works

The tester measures the rate of heat transfer from the tip to the gemstone. Diamonds, being the most thermally conductive of all natural gems, produce a distinct signal that the device instantly interprets. For jadeite, the device compares conductivity against a calibrated baseline, ensuring you can distinguish genuine jadeite from synthetic or lower‑grade alternatives.
