The GemPen® Premium provides professional users with the means to efficiently determine whether a diamond/sapphire or ruby is a natural, synthetic or heat-treated gemstone.
The GemPen® with complementary aids can make it possible for the user to identify sophisticated synthetic gemstones on the go, saving valuable time in the valuation process. The key word here is “on the go” as it is unusual to get reliable results for certain types of synthetic gemstones without sending them to a gemological institute for validation, something that can take weeks.
emological equipment such as the GemPen® have become necessary in recent decades because of the large amounts of synthetically manufactured gemstones in circulation that create uncertainty in the valuation process, as synthetic gemstones can be chemically, physically and optically identical to naturally occurring ones.
When testing gemstones with the GemPen, you can determine if a gemstone is a natural, CVD or HTHP stone. The GemPen will also highlight filled inclusions on diamonds, sapphires and rubies.
The light emitted by the filter will provoke a fluorescent light to be emitted by the HTHP/CVD diamond but the natural diamond will remain unchanged. The GemPen Premium includes all the different filters to screen and analyse Diamonds and to give indications on flame-fusion (Verneuil) lab-created blue Sapphires. The LW Filter 4 (in combination with Filter 1) helps the user to distinguishing between a natural fluorescing diamond and a synthetic one. Filters 2 and 3 are used to screen for Heat, Beryllium and other treatments.
