Advanced Diamond Tester Calibration for Lab-Grown Detection
The diamond testing industry faces an unprecedented calibration crisis. Conventional wisdom holds that a modern thermal/electrical conductivity tester is infallible against natural diamonds, but this is a dangerous oversimplification. The true battleground has shifted from natural-simulant differentiation to the nuanced identification of advanced chemical vapor deposition (CVD) and high-pressure, high-temperature (HPHT) grown stones, which share […]
