Includes GemPen® Premium and Darkroom
To work with ‘GemPen® Premium’, formal gemmological knowledge and understanding of transition elements is required to effectively interpret the results on rubies & sapphires. ‘GemPen® Premium’ should always be used in combination with other gemmological instruments when screening rubies & sapphires for synthetics & treatments.
GemPen® Premium is the most complete kit that we have to offer; it includes all the different filters to screen and analyze Diamonds and to give indications on Corundum (Rubies & Sapphires). The included LW Filter 4 (in combination with Filter 1) helps the user to distinguish between a naturally fluorescing diamond, lab created diamonds or an HPHT treated natural diamond. Filters 2 and 3 are used in combination with Filter 1 and 4 to screen for synthetics and flame-fusion (Verneuil), as well as heat, beryllium, and other treatments.
GemPen® Darkroom allows the professional user to create a portable environment, making it easier to more accurately interpret results. This complimentary tool contains a UVB protective filter viewing glass to better observe fluorescence and phosphorescence effects in natural, synthetic and treated gemstones. The Darkroom allows the user to work hands-free with their GemPen® and has three variable functions: screening single stones, multiple stones and rings.
