HOW RELIABLE ARE DIAMOND TESTERS? – WHAT ABOUT CUBIC ZIRCONIA AND MOISSANITE?
Of the two most common diamond simulates, Cubic Zirconia (including ‘diamond-coated’ Cubic Zirconia) presents no problem at all but Moissanite needs a special mention. Moissanite is a purely synthetic stone (ie it is grown in laboratories by man, it does not exist in nature) and it registers as diamond on diamond testers. This is an unfortunate fact of physics, that Moissanite has the same thermal properties as diamond. So how do you tell Moissanite from diamond? There is another electronic tester, it looks (and operates) just like a diamond tester though it works on an entirely different principle. Or there is a combined electronic tester for diamond and Moissanite. Do you need a diamond tester and a Moissanite tester? Most people buy only the diamond tester; most people buy the diamond tester “just to start with” and some buy the Moissanite tester. Do you really need a Moissanite tester? Here are two fascinating facts that might help you make your decision: FACT 1. Moissanite was fir
