FURTHER INFORMATION 

Have you seen the Fascinating article about gem testers? This will answer many questions about electronic gem testers (all electronic gem testers!) - how 'reliable' are they? How 'easy to use' are they?

In summary: no gem tester will light up with a number (or name) that tells you, with 100% certainty, the name of the gemstone. This is because nature does not make gemstones to a standard formulae, there are always variations. To see how the readings of gemstones overlap, see chart.

All of gemmology is a detective game, starting with an idea of what the gemstone might be (that is what electronic gem testers are for) then using knowledge and skill to find the answer.

If you are new to gemmology, please DO buy this gem tester! - but also buy a good book about gemstones, the best is Gem Identification Made Easy. Not only is this a good guide to gemstones, it also has details of every gem tester, including hints, tips and advanced instructions.

QUESTIONS & ANSWERS

Ask a Question
  • Hi there, does it accurately determine jadeite from jade or does this machine just group them both under jadeite and spinel ? What do we need to determine jade from jadeite ? Thanks

    Will this tester determine jadeite jade from nephrite jade: yes.  

    Will this tester accurately determine jadeite jade from nephrite jade: no.

    There is 'overlap' between readings, see our chart.

    Spinel is a totally different stone and has a significantly different reading. You shouldn't need a tester to tell spinel from jade.

  • Hi, does this device give results for Paraiba Tourmaline gemstone, obviously it needs to identify the copper content in the stone. I see on the picture it just states Tourmaline on the spectrum window. Thanks

    Simple answer: no.

    Complicated answer: this tester is a thermal meter not a spectroscope (there is no 'spectrum'); it won't show you the transitional elements; it won't detect if the stone contains copper.

  • On the tester how do you know if it’s a diamond or mossanite ?

    This tester will not distinguish diamond from Moissanite. You would need either a dedicated multi-tester diamond tester (e.g. MULTI-EXPP or MULTI-SAM) or a more sophisticated gem tester (e.g. REFRACT-DIGI-PRESID or GEMTEST-DUO-II).
