The cardboard box: in addition to DIAMOND SELECTOR II it has the CULTI logo on four sides, and Made in Japan culti on two sides. If it has no instructions at all, be suspicious. If the instructions don't seem to tally with what you have in front of you, be suspicious. If there's no guarantee slip, be suspicious. The pouches vary a lot on the copies, some are thin vinyl, on some the stone-holder compartment is fastened with Velcro flap. Thermal conductivity testers rely upon the truth that gemstones, glass, or cubic zirconia behave in warmth differently. Therefore, diamond testers are constantly correct approximately their findings.

Highly sensitive tester: professional diamond selector iii shows real diamonds or fakes, lcd display and led display. compared to generation ii, the sensitivity and accuracy have been significantly improved. If a stone is very hot, it will feel warm-to-the-touch even if it is diamond, and will not register DIAMOND on a diamond tester. This happens when a diamond is taken from a shop window where hot lights or sunshine has heated it. It can be a problem in a heat wave, as the temperature approaches 30 degrees. Generally, high temperatures are not a problem here in the UK / Northern Europe. Remember to set the number according to the size of the stone you want to test. The bigger the stone, the lower the number you set. And the smaller the stone, the higher the number you set. Step 2: Uncap the Selectormagnification]: 60x led magnification with batteries ( small microscope ). for gems, coins, antiques, stamps, reading, inspection etc. Led light and audio result indication.the red light will be showed and the audio indicator will ring if the stone is real diamond. design]: this tester comes with a small testing platform for holding loose stones. it can simple calibration for stones of various sizes and even for a new beginner.

Some diamond selectors use electricity in the place of heat. A few even combine electricity and heat.easy to use】: green indicator will be showed on diamond selector ii if the stone is a real diamond. it will make continuous buzzing sound when user accidentally touches metal rather than stone. Just pressing the test tip is enough. Don’t move it on the diamond or you risk breaking it due to the hardness of the gemstone. A warm diamond won’t read correctly so some of the tests may be incorrect. Therefore, allow the diamond to cool if it gets warm before you run more tests. Sensitivity If your tester works consistently (it gives the same reading on the same stone every time) and correctly (it accurately identifies stones) then you really don't need to know the principle on which it works. However, if you are having problems (and you have read the instructions and are certain you are using it correctly) - then a knowledge of the principle will help. Diamond testers are ever-correct tools. They assist in perceiving proper diamonds at a genuine moment. Unfortunately, thermal conductivity testers may be defective while moissanite is at hand. This is due to the fact that moissanite and diamond behave warmly at a comparable rate. But that shouldn’t freak you out due to the fact that electric conductivity testers are available in handy. Despite the 2 stones sharing identical thermal conductivity, moissanite and diamonds have exclusive prices for engaging in electricity. And that could be trouble solved.

You can also see, from the principle that you can accidentally make a circuit and get a MOISSANITE reading: by touching the setting of the jewellery, OR by placing the probe tip very very close to the setting so that the electricity 'jumps' - which is why you can't test very tiny stones (e.g. about 1 point). A layer of grease (and some proprietary jewellery cleaners) is likelty to be electrically conductive, so that diamonds will register as MOISSANITE - the stone must be clean, wipe it carefully with a very clean cloth (or clean it with an alcohol). MULTI TESTERS

DIAMOND TESTERS

Diamonds read DIAMOND based on thermal conductivity, all the rules and conditions listed above apply. Fast testing and portable design: it is designed for fast, accurate and safe diamond testing. non-destructive testing makes it easy and accurate to use. with metal warning function, it will continuously buzz when metal is accidentally touched. the tester is lightweight and compact in size (with a credit card), easy and convenient to carry. The purpose of a Multi Tester is to show you if the stone is diamond or not diamond. It carries out the diamond test (see above) then, a fraction of a second later, it carries out the Moissanite test (see above) and its microchip combines both readings and calculates a response. Place the cap in a safe place so you don’t lose it. There is no other way to protect the fragile tip of the selector. Step 3: Test the Diamond
