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?

The result of each test is usually a list of 2 or 3 or 4 stones; you can narrow this down by entering its colour - but you will end up with more than one possible stone, and you then have to decide which one it is. There is no gem tester (apart from Moissanite/Diamond testers) which will give you one 'definite' answer.

There is a useful chart showing how the readings of the main gemstones overlap, click here. YOU DON'T NEED THIS CHART TO OPERATE THE TESTER! - the tester is fully self-contained, the names of the gemstones appear on the display. However, the chart is useful because it shows you which stones give the same (or similar) readings.

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. 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.
