Filter 4:

The LW Filter 4 (in combination with Filter 1-Included in your GemPen®) helps the user to distinguish between a natural fluorescing diamond and a lab-created diamond.



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 lens to better observe fluorescence and phosphorescence effects in natural, synthetic and treated gemstones.
