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. Setting the sensitivity is important but not as important as the speed at which the lights move on the segments. The speed actually tells you whether or not you have real diamond. Some diamond selectors use electricity in the place of heat. A few even combine electricity and heat. The thermal conductivity meter is designed and manufactured according to the thermal conductivity of diamond. it is specially used for the identification of the true and false of diamond. 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. ConclusionSo 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. So to set it, turn the Volume knob until the segments light up. Take a look at the number chart on the label of the selector. If the temperature where you are is not cold, set the start number at 4 if you have a small or medium-sized stone. But if you have a large stone, choose 3. 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.
