JEM-III is a sure way to tell the difference between diamonds and moissanite (man made diamonds). This tester will leave you in no doubt as to the nature of your stones. It is a "touch and tell you" device that utilizes the moissanite feature, the different electrical conductivity from diamond. It effectively and quickly distinguishes moissanite from diamond. With the addition of the Ultraviolet (UV) light you can now test the flourescent reaction of stones.
