GemPen®, the new portable screening device for diamonds, has just been included in the curriculum of the Spanish Gemological Institute (IGE). The decision was made after it managed to 100% correctly identify a mix sample of 71 colorless HPHT-, CVD- and natural diamonds.
Tests were performed on 71 colorless diamonds from the IGE gemstone collection, where mounted diamonds and melee diamonds (smaller than 0.15ct) were included in the testing. The sample contained 25 natural, 25 synthetic HPHT and 21 synthetic CVD diamonds. GemPen® identified all stones correctly.
The new screening device utilizes UV-light technology with a unique combination of wavelengths and filtering. Once turned on and directed towards a diamond, the USOF (Ultra Spectrum Optical Filtering) technology enables display of unique fluorescence effects, providing results on treatments and synthetics that are not visible using standard UV-light products. An additional complimentary tool is the Gemstone Map, an image bank of reference diamonds tested by GemPen® that illustrate different fluorescence effects.
Founder of Gemometrics and inventor of GemPen® is renowned Swedish gemologist Torbjörn Lindwall.
