With its retractable thermoelectric probe tip, ultra-thin design, and instant testing capabilities, it ensures accurate results for diamonds as small as 0.01ct. The device features an easy-to-read analog display and built-in reference discs, making it an essential addition to any gem testing toolkit. ## Description The Gem Tester with color estimator display for smooth, seamlessly testing of precious gems and diamonds. The SmartPro Gem-Eye I was specifically developed to distinguish between diamonds and other simulants, using the principle of thermal conductivity. The exceptional heat conductivity of diamonds is unlike any simulant. Therefore, diamonds are not easily replicable. The SmartPro Gem-Eye I consists of two linked thermometers; 1 that is heated electronically, while the other is cooled by the gem being tested. The difference in temperature creates an electrical output, which is then amplified and displayed on an analog dial. The color gem estimator display assists the user in distinguishing popular colored gems from each other. Review: The product is defected one. It couldn't connect to the power. - The product was a defective one, and it couldn't connect the power. It was a total waste of money. I will strongly encourage you not to buy this product. The seller knew it wasn't working, and yet they sold it. This is disgustingly greedy. I wish I could get my money back. Unfortunately, I sent the product to India. shipping and custom clearance will cost me more I guess.
