| THE PRESIDIUM DIAMOND FACT is the most affordable protection against simulated diamonds in the market. It is your defense against financial loss and the invaluable reputation you work to protect.
Industry Proven Thermal Testing
The battery powered DIAMOND FACT uses thermal conductivity to distinguish diamond from its many simulants. Simply touch the tips of the probe pen to any mounted or loose stone. If the analog dial reaches the green zone, the stone is diamond, if it remains in the red zone the stone is a simulant. Stones as small as 0.02 carat can be accurately tested.
Heat conductivity of diamond and some of its simulants
The graph illustrates typical experimental observations of heat conductivity measured in millivolts against time after the probe makes contact with different stones of similar size.
Fail-safe Protection
The unit includes a built-in diamond and simulant test discs for easy calibration. The units probe pen comes with a Metal Alert Buzzer to let the user know if a metal mounting has been touched.
