Thermal meter, same as the standard model above. Works with loose stones and also stones mounted in jewellery.

In addition, it has a reflectivity meter. This gives the result as a number which you look up on a chart. The chart includes 76 common gemstones, and we include two versions of the same chart. The first is in numerical order, so you can look up the number. The second is in alphabetical order of gemstone - so if you already have a good idea as to what the stone is, you can see how closely the reading on the machine matches it.

Calculates refractive index by measuring reflectivity. Contains a database of over 200 stones, so instead of giving a reading in numbers (as with the Prsidiums) it gives a list of possible stones for that reading.

This is a set of 'difficult' stones that are confused with diamond, not so much because they look like diamond to a diamond expert, but because they are very hard to measure on machines: YAG, GGG, synthetic sapphire, synthetic spinel, zircon, strontium titanate and cubic zirconia.

Brilliant-cut cubic zirconia, 5mm diameter (measures about 30 points on a diamond gauge).

TRADE DESCRIPTION:

As an expert, YOU can probably tell Cz from diamond at a glance. But to your customers, Cz will look identical to diamond. And your customer will be impressed when you show them how easily you can distinguish between the two with your tester.
