How does a moissanite tester work?

A moissanite tester works to measure the electrical conductivity of the stone. A moissanite stone will have a little bit of electrical conductivity while the diamond will not. If you do get some electrical conductivity, then this means the gem in your hand is a moissanite.

Is diamond Selector accurate?

Diamond testes are probably the most accurate and reliable tools to check the authenticity of a diamond. However, it is worth mentioning that electrical conductivity diamond testers and multi-testers are much better than thermal conductivity testers. Although they are higher in price, they are much more accurate.

How accurate is Presidium Gem Tester?

The presidium gem tester is not considered to be very accurate. You don’t see serious gemologist using them. If I was to own just one tool it would be a refractometer.

Does moissanite get cloudy?

Natural mineral called silicon carbide is where Moissanite grown from. Therefore, Moissanite will never become cloudy, discolour or change its appearance. A Moissanite will maintain its brilliance, colour and clarity for a lifetime and beyond.

How do I know if my moissanite is real?

The most effective way to tell Moissanite apart from a diamond is to use a loupe to look through the top, or the crown, of the jewel at an angle. You will see two slightly blurred lines that indicates a double refraction, an inherent quality of Moissanite. Double refraction is easier to see in some shapes than others.

Is the diamond selector 2 accurate?

How Reliable Are Diamond Testers? Diamond testers are one of the most accurate tools to check a diamond for authenticity. However, you should know that testers that rely on thermal conductivity can mistake a moissanite for a diamond because these two stones are very similar in the way they conduct heat.

Will a diamond tester work on Jade?

However, it really does — and not just for diamonds. It can detect authenticity of diamonds and other gemstones such as rubies, sapphires, jade, and agate.
