Full support given for items you buy from QUICKTEST. Alternative gem testers Please note, none of these testers will distinguish natural stones from synthetic stones.

Standard Presidium Electronic Gem Tester (model PGT II)
Great for checking out small stones on jewellery, separates the garnets from the rubies, the glass from the diamonds and the topaz from the sapphires. You do need to calibrate it when it first arrives

DETAILS <p>We are a UK company offering fast delivery and easy telephone support.</p> <p>Bench model. Thermal meter, tests for 17 common groups of gemstones (about 40 varieties), enlarge the product picture to see the scale in detail.</p> <p>Works with any stone, loose or mounted in jewellery, even uncut stones. The only condition is that the stone (and tester) must be at room temperature. </p> ACCESSORIES <p>Included:</p> <p>Strong nylon carrying pouch</p> <p>Instruction book</p> <p>PP3 Battery</p> <p>Mains power adaptor</p> FURTHER INFORMATION <p>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?</p> <p>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.</p> <p>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.</p> <p>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.

Brilliant machine really pleased.

Very strange, since we are unique in that we open and carefully check every single tester before dispatch; however, if there is a problem it is better to call us and we will tell you which buttons to press to fix it, rather than leave negative feedback.
