Fortunately, the development of generation is making matters greater handy with new diamond testers which have proved useful for genuine situations. But how do those diamond testers work, and how dependable are they? Read directly to analyze greater diamond testers. What is a Diamond Tester? So if the lights move rapidly, lighting up as they go, you know you have a diamond. This is even if you start at the wrong start number. But if they are slow, you may not have a diamond. There are variations from manufacturer to manufacturer but, typically, 4 red then 5 orangey-yellow then 3 blue. 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 Selector The LED lights are what tell you whether or not the stone you have is a diamond. The starting number does not exactly matter. But it is there to guide you until you grasp how to use the selector.

The instructions are on glossy paper in reasonably good English, and the guarantee slip is in English too. Relatively cold" stones give a high (and for large diamonds, lightning-fast) reaction on the LED segments. 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. New Adjustment Firstly, a very rare type of diamond (imaginatively named Type II). These are indistinguishable from other diamonds. It's merely a quirk of their chemical composition that they happen to be electrically conductive - which is why they register MOISSANITE on multi testers. These are rare, you might never come across one, but they do exist, they turn up regularly at gem laboratories, to settle disputes arising from the use of testers.

However, this machine can make mistakes and it isn’t perfect. While the diamond selector can tell the difference between a real diamond and a fake one, it cannot differentiate between a diamond and moissanite. Diamonds and moissanite conduct electricity and heat differently. Therefore, the diamond selector must be used with caution. You should also pay attention to the setting sensitivity and the speed at which the segment lights will flash to determine whether the stone is real or not. Conclusion Touch a stone gently against your lip. Plastics (and, to a lesser extent, glass) feel 'warm' whereas sapphires, rubies and diamonds feel icy cold. This 'relative coldness' is what the diamond tester is measuring, technical term thermal conductivity. Despite the fact that a diamond selector is pretty reliable, it can also make mistakes. It cannot tell the difference between a moissanite and a diamond. I know it looks like a lot right now but trusts me, you will get the hang of it with time. However, if you have any questions, feel free to ask them in the comments section.

4 Easy Steps to Use a Diamond Selector II - Something Borrowed

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. A diamond tester is a tool used to test the authenticity of a specimen stone via means of trying out thermal or electric conductivity. If the specimen stone meets herbal diamond examined properties, it\’s going to imply or provide an audible signal. Diamond testers are the portable, way to their small frame sizes. How can you use it?The availability of greater actual and faux diamonds available in the marketplace can result in surprisingly precious or maybe nugatory portions of rings. 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 With time, you will understand how a diamond selector works. You may not even need to consult the number chart anymore if you keep using it. Important Note You’d need to press down the probe’s tip on the proper perspective at the stone. Just ensure now no longer press the tester at the stone at much less than ninety degrees. And if the lights illuminate slowly and doesn’t read diamond, it means the stone is likely another gemstone like sapphire.

OTHER STONE, if it's medium thermal conductivity, especially rubies and sapphires, plus anything really cold (which would give a 'slight' reaction on a standard row-of-LED-lights diamond tester) This is because a moissanite and a diamond conduct heat just the same. However, they don’t conduct electricity the same way.

What Does Green Mean On A Diamond Tester?

Before using the diamond selector, you should know how to read the tester. To use it, you must make sure that your hands are moist. This is because the device cannot detect the diamond if they’re dry or have been covered in vaseline. Make sure that you use your left hand when you hold the device. The diamond selector has several settings that can help you determine the size of the stone. Once you’ve set the size, the device will display the number of the stone.
