What is a Diamond Tester?
A diamond tester works by checking the properties of a diamond to determine its authenticity. It’s an essential tool for a professional jeweler, avid collector, or anyone who wants to know if a gemstone is real or fake.

Do jewelers have diamond testers?
A diamond tester is a professional electronic device used by jewelers or jewelry enthusiasts to detect natural diamonds.
Will a cheap diamond tester work?
Yes, most inexpensive electronic diamond testers rely on the fact that diamond is a better conductor of thermal energy (heat) than is Sterling or pure silver. Most other stones that might be mistaken for diamonds are thermal insulators.
Can fake diamonds beat a diamond tester?
Yes, some diamond simulants can pass a diamond tester. For example, moissanite, a man-made gem, may pass as a diamond on a standard tester pen. This is because moissanite also has very high thermal conductivity!
Can diamond tester tell lab diamonds?
Will Lab Diamonds Pass A Diamond Tester? Yes, lab diamonds have the same carbon composition as natural diamonds.
Therefore, they have the same thermal conductivity. The test results are positive when exposed to the diamond tester, since the diamonds have the same physical and chemical properties as natural diamonds.
Are diamond testers 100% accurate?
Are Diamond Testers Accurate? Diamond testers are perhaps the most accurate and reliable instruments to test the authenticity of a diamond.
However, testers that measure thermal conductivity cannot tell an authentic diamond from moissanite because these gems are similar in heat transfer.
