What is a diamond tester?
Diamond Tester is a portable device that helps test diamond in a go, it is so small that it can be put in your pocket. The tester is a small, needle-like tip that needs to be placed on the diamond to be tested. If the diamond is real, the device indicates that on its display or with a beep-beep sound signal.
How does a diamond tester work?
The old Diamond Testers have a metal tip that is heated and then applied on the comparatively cooler surface of a diamond. Heat transfer occurs and the diamond surface is heated by the tip. If the heat reading of the testers and the diamond match, this indicates that the stone really is a diamond.
Types of diamond testers
There are various types of Diamond Testers available in the market today. The conventional heated tip method is largely being replaced by other methods of conduction or a modification. In the case of Synthetic Diamonds, the most viable option is the Electrical method or the UV testing Method.

How do diamond testers work?
A basic diamond detector uses its heated needle tip made of metal to cause a heat transference once placed on the diamond’s surface (thermal conductivity). You will then get a result that will let you know if the diamond is real or fake.
Is a moissanite a diamond?
