GemPen Premium is the most complete kit that we have to offer; It 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.
Below is a Tutorial Video that shows how to screen diamonds using GemPen:
