It uses advanced dual thermometer technology to measure thermal conductivity, enabling precise identification of diamonds as small as 0.01 carats. The integrated color estimator display enhances gem differentiation, making it an essential tool for professionals demanding accuracy and efficiency. ## 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 og dial. The color gem estimator display ists the user in distinguishing popular colored gems from each other. ## Features - High efficiency gem tester - Retractable thermoelectric probe tip ensures constant pressure between probe tip and gemstone - Industry’s thinnest probe tip (0.48mm) - Tests diamonds as small as 0.01ct - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Grobet | | Part number | 56.926 | | Item Weight | 839 g | | Package Dimensions | 23.19 x 16.61 x 15.29 cm; 839 g | | Item model number | SPGE-I | | Colour | Black | | Style | Compact | | Power source type | Battery Powered | | Item Package Quantity | 1 | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Brand:** Grobet USA - **Power source:** Battery Powered - **Style:** Compact - **Colour:** Black - **Measurement type:** Thermal Conductivity ## Images ![Grobet 56.926 SmartPro Gem-Eye I LED Indicator Gemstone Tester - Image 1](https://m.media-amazon.com/images/I/51HJ9H1bcHL.jpg) ## Customer Reviews ### ⭐ The product is defected one. It couldn't connect to the power. *by K***N on Reviewed in the United States on 16 September 2022* 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. ### ⭐⭐⭐⭐ Good *by D***E on Reviewed in Canada on 25 January 2020* product is ok, but the price to high,. ### ⭐ Not working, Defective *by R***. on Reviewed in the United States on 12 April 2021* Takes forever to warm up, they sent a open defective one, not new, seal sticker was broken.
