Moissanite tester by GemTrue (Moissanite Plus)

Summary Must be used in combination with a diamond tester,  i.e. if a simple (thermal conductivity) diamond tester says the stone might be diamond or Moissanite (you won't know which!), test it on this to see if it's Moissanite.   Accuracy / Guarantee A 'Moissanite' reading on this tester indicates that there's a probability that the stone is Moissanite. It is not guaranteed, the latest Moissanites will show up as diamond on this tester and most synthetic diamonds show up as Moissanite. In addition, the slightest layer of grease on the stone (e.g. by touching it with your finger) will give incorrect results.  All testers have their limitations, see our article about how to choose a diamond tester.

Full support given for items you buy from QUICKTEST. Alternatives The MOISSANITE tester detects most Moissanites. However, you must only test stones that you think might be diamond (e.g. you have tested them on a thermal diamond tester). For a summary of all diamond and gem testers see the Comparison Chart, or see a more detailed explanation of what the various types of tester can (and can't) detect at our Guide to Buying Diamond Testers.
