You might have heard that there are a lot of ways to tell whether a diamond is real or fake. The problem is that most of these methods are not 100% reliable. Using a diamond tester, however, is one of the surest and fastest ways to check if you have an original diamond. A diamond tester is a portable device that you can put in your pocket. The tester has a small, needle-like tip that needs to be placed on the stone tested. If the diamond is real, the device indicates that on its display or with a sound signal. Diamond testers’ principle of operation is based on the fact that different gemstones conduct heat differently. Heat passes through a diamond in a different way than it would through cubic zirconia or glass. A diamond tester will detect the rate at which heat moves through the stone and will tell you whether it is a real diamond. There are also testers that use electrical conductivity to test stones – they are based on a similar principle, but they use electricity instead of heat.
