GemOro Diamond Testers Editorial Review
The GemOro Testerossa Diamond Tester has garnered a mixed reception among users, with a significant focus on its capabilities and accuracy in differentiating between various gemstones, particularly diamonds, moissanites, and sapphires. Customers appreciate its unique features, including vocal prompts and visual indicators, which provide clear identification of the stones being tested—green for diamonds, blue for moissanites, pink for sapphires, and red for metal contact. Many users find the device easy to handle, thanks to its ergonomic design, and some praise its accuracy. Positive reviews highlight that the tester works dependably with diamonds and moissanites, providing correct readings most of the time, although a few users reported some anomalies. For instance, testers exploring both natural and lab-grown diamonds experienced confusion with the device yielding incorrect results under certain conditions, especially when the gemstones were contaminated with substances like oil. On the downside, several customers faced issues related to the product's build quality. Reports of components such as the name plate detaching and a problematic battery compartment were prevalent. Some users pointed out inConsistencies, expressing disappointment over its reliability in testing lab-grown diamonds, which contributed to frustrations, especially given the high cost of the tester. Despite some inaccuracies, many still recommend the Testerossa for basic diamond and moissanite testing—while caution is advised for professionals needing precise lab-grown diamond differentiation. ###
