Lab diamonds are comprised of the same chemical makeup as real diamonds. You should get a result in about three seconds. You might be asking well what about man-made diamonds (Lab Diamonds)? Moissanite testers that do not work on some odd moissanites work perfectly when the stone is exposed to UV light. Diamond testers will tell you if the gem is real by measuring the amount and speed with which heat travels through the stone. Diamond testers measure thermal conductivity in a gemstone. The latest diamond testers on the market now include both thermal and electrical conductivity tests. This needle works with thermal connectivity to give an accurate result. Here, the first (probe) and second (clip) contacts of the circuit couple the high voltage to the gem under test, while a low-impedance detector circuit is used to flag when the contacts are erroneously contacting each other during measurement. Moissanite testers work by measuring electrical conductivity through the stone (diamond is not electrically-conductive, and moissanite is). Hence, it is advisable to use other testing equipment to supplement the thermal conductivity test. Multi-testers are obviously more expensive, but there’s a convenience to only needing to have one tool on hand in order to get the information that you need on a particular stone. Within a split of a second, the test … However, there is a very rare type of diamond (type II diamond) that has an unusual chemical composition that makes it electrically conductive. The Presidium Moissanite Tester II (PMT II) measures the electrical conductivity of the gemstones directly, determining if the gemstone is a genuine diamond or a moissanite (a diamond simulant).
