How Do You Know Your Gems Are Real?
If you work in the jewellery trade or are simply just curious to find out whether your own gemstones, or ones you are about to buy, are real or fake, then the diamond selector is for you. It's easy to use even for beginners the simple handheld testers have an LCD display, LED lights and emit audible sounds to give accurate readings time after time. It is a sure way to tell the difference between fakes and the real deal, the selector will leave you in no doubt as to the authenticity of your stones:

Clean your stone before testing - grease and other dirt can give inaccurate test results
Touch the probe of the selector to the stone you are testing

If it’s a fake (glass for example!) there will be no reaction
