Review on 🔍 Authenticity Verifier: Presidium Adamas Diamond and Moissanite Tester for Diamond Authentication by Karla Richter

later Handheld testers are divided into three types: thermal conductivity testers, electrical conductivity testers and multi-type testers (electrothermal = both thermal and electrical conductivity). The simple diamond tester only tests thermal conductivity. Diamonds conduct heat at a high level. CZ is not a good conductor of heat, so CZ is easy to separate. The problem, however, is that moissanite is a high conductor of heat and the basic diamond tester will give a false positive reading for moissanite. Adamas is an electrothermal multitester that can measure both thermal and electrical conductivity. It is important to clean the stones before testing. The retractable tip is only accurate when the stones are clean, so clean or rub the stones to remove oils/dirt and avoid false readings. Although Adamas is accurate and very easy to use, I'm deducting a star because it's not very good. the price of money. You can buy two simple testers for a fraction of the cost: a thermal tester (diamond/CZ) and an electrical tester (moissanite). However, for convenience and accuracy, Adamas is the gold standard. I recommend it anyway, even if it's a bit pricey.
