Moissanite Testers
A moissanite tester will distinguish diamond from moissanite.
Diamond Tester Moissanite Tester Diamond-Moissanite Tester
Moissanite is manufactured in the United States by Charles & Colvard, Ltd. It is a potentially beautiful synthetic gemstone that looks like a diamond to the naked eye. It also conducts heat at the same speed as a diamond, so a diamond tester conducting heat conductivity testing (which is how most diamond testers work) will not distinguish it from a diamond. A moissanite has a value of 10% to 15% of the value of a diamond of similar weight and clarity. So if it is a diamond you are intending to buy, you can lose a lot of money by accidentally taking home a moissanite.
You can distinguish diamond from moissanite in many ways. For example, you can try a scratch test, because moissanite is softer than diamond. (Diamond hardness is a 10 while moissanite is 9.25.) The problem with the scratch test is that you can ruin some valuable moissanite, and in fact, put scratches in actual diamond. This is because diamond has different degrees of �directional hardness� and the hard diamond point will scratch against any diamond facet presenting a slightly softer hardness direction.
The most convenient way to test for moissanite is to use a moissanite tester. A moissanite tester puts an electrical current into the gemstone, and then measures how well the stone conducts the electricity as compared to a diamond. This method is fast, especially if you are testing multiple stones.

If you already own a diamond tester and you just want to add a moissanite testing capability consider the Moissanite Tester II by Presidium:
"PRESIDIUM MOISSANITE TESTER" uses the technology of Capacitance and the capacitive measurement of electrical displacement. The Moissanite tester is designed specifically for identification of Synthetic Moissanite mounted on metals. The measuring procedure is very simple by touching a high sensitive measuring probe made of special grade polymer and the reading is instantaneous. Note: The Presidium Moissanite Tester is recommended to be used after positive testing result for Diamond with a Thermal Conductivity Tester.
