With the increasing presence of CVD/HPHT synthetic diamonds on the market, consumers and businesses need more advanced methods to identify these products. The price of artificial diamonds is only 30% of that of natural diamonds. However, synthetic diamonds from CVD HPHT methods are increasingly advanced and are truly indistinguishable by eye or conventional diamond testing equipment. And to solve this problem, the GemPen diamond scanner has been launched to help identify diamonds created from the HPHT & CV laboratory.
GemPen provides users with the means to effectively determine whether a diamond is natural, synthetic (man-made), or treated (visually enhanced to increase value). This tool is portable, durable and gives instant results. GemPen is used to confirm gemstones.
GemPen can help identify different treatment methods (HPHT, CVD, irradiation, etc.) in natural and synthetic gemstones. GemPen uses high-power UV light and specific wavelenght filters to induce quenched fluorescence or phosphorescence in the gemstone.
GemPen is a diamond verification tool for loose and mounted stones, designed to separate diamonds from synthetic diamonds. It is suitable for field gemologists, diamond buyers, wholesalers and retailers.
GemPen Darkroom allows users to create a portable environment, making it easier to interpret results more accurately. This free tool features a UVB protective filter viewing glass to better observe fluorescence and phosphorescence effects in natural, synthetic, and treated gemstones. The darkroom allows users to work hands-free with their GemPen® and has three different functions: screening single stones, multiple stones, and rings.

How to distinguish diamonds by looking at them
Diamonds that only fluoresce in a blue-white color can be identified as natural diamonds
Diamonds that fluoresce in other colors can be identified as synthetic diamonds
Diamonds that fluoresce in other colors and in some cases also show some phosphorescence can be identified as synthetic diamonds
Diamonds with moderate to strong greenish yellow fluorescence and strong luminescence can be identified as synthetic diamonds (usually HPHT).
Diamonds with purplish blue fluorescence indicate that natural diamonds have been HPHT treated
Fluorescent and phosphorescent diamonds with a deep blue color can be identified as synthetic diamonds
