Review: Not bad, not bad! - Really cool and accurate tester. Talks and lights up according to stones. Very accurate. Moissanite and Diamonds can get similar readings though. Identifies sapphire and let's you know if you hit metal. Review: Stopped working after only one use - I used this tester when I first got it and everything seemed great. Went to use it again a few days later, and multiple times since then, and only registers each stone as a diamond. I can test it against gold and it still reads "diamond", no matter what I test it on. I followed the user guide on cleaning the tip and resetting the tester, and still doesn't work. Wish I could return it. ## Features - Country Of Origin: China - Model Number: 0770 - Item Package Dimension: 25.0" L x 14.0" W x 17.0" H - Item Package Weight: 2.0 lb ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006PK1OS6 | | Best Sellers Rank | #111,514 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #48 in Jewelry Diamond Testers #15,000 in Jewelry Accessories | | Brand Name | GemOro | | Color | Silver | | Customer Reviews | 3.7 out of 5 stars 243 Reviews | | Display Type | LED | | Form Factor | Handheld | | Global Trade Identification Number | 00854413003772 | | Item Height | 1 inches | | Item Type Name | 0770 Testerossa "Talking" Diamond, Moissanite & White Sapphire Tester | | Item Weight | 1.5 Pounds | | Manufacturer | GemOro | | Material Type | Polycarbonate, Rubber | | Measurement Type | pounds | | Readout Accuracy | 0.01 pounds | | Special Features | Talking, UV-F1 Moissanite Identification Technology, Metal Alert Warning | | UPC | 854413003772 | | Unit Count | 1.0 Count | | Warranty Description | 1 year warranty. | | Weigh Scale Type | Balance Scale | | Weight Capacity Maximum | 2 Pounds | ## Product Details - **Brand:** GemOro - **Color:** Silver - **Special Feature:** Talking, UV-F1 Moissanite Identification Technology, Metal Alert Warning - **Display Type:** LED - **Weight Limit:** 2 Pounds ## Images ![Testerossa Diamond Tester | Test Diamond, Moissanite, White Sapphire Gemstone | Precision Tool with Expert Professional Reading & Accuracy - Image 1](https://m.media-amazon.com/images/I/51ThoqEKk6L.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Does this come with a charging stand?** A: Yes.
