Diamond and Gemstone Tester FAQs

How Does A Gemstone Tester Work?

All precious stones have individual heat conducting characteristics that tell it apart from others. A gemstone tester sends heat through a stone to measure how fast the stone conducts it. Depending on the result, a type of gemstone will be identified.

How Accurate Are Diamond Testers?

High quality diamond testers are the most accurate tools to check if a diamond or gemstone is authentic. You should only buy these tools from reputable retailers or distributors to ensure that quality is assured.

Which Is The Best Diamond Tester?

There is no one best diamond tester on the market. What matters is what features are necessary and which product offers these features.

How Much Are Diamond Testers?

Our diamond testers range from £149 to £6,495 depending on the style, brand, and accuracy that you require from our testers.

Can A Diamond Tester Test Other Stones?

A diamond tester can test other stones for authenticity. For instance, a diamond tester can test rubies, sapphires, crystals, agate, jadeite, etc.

Can You Test A Ruby With A Diamond Tester?

Yes a diamond tester can test rubies, as well as diamonds, sapphires, crystal, and many more stones.

Will Moissanite Pass A Diamond Tester?

The heat conductivity of moissanite is very close to a diamond, so a diamond tester of lower quality might not give you a definitive result. If you have concerns about this you should invest in a superior, quality assured diamond or gemstone test.
