SAM by Presidium | Advanced Diamond and Moissanite Tester with Thermoelectrical Probe | Detects Low Conductivity Moissanite | 0.01–10 Carat Diamond Testing Tool

The SAM Diamond & Moissanite Tester by Presidium is a next-generation diamond testing device designed to accurately distinguish diamonds from an expanded range of moissanites — including the increasingly common low electrical conductivity moissanite manufactured worldwide. Using a highly sensitive thermoelectrical probe and enhanced detection algorithms, SAM provides superior resolution and reliability compared to traditional diamond testers. Its advanced technology enables consistent identification across a broader spectrum of diamond simulants, making it an essential tool for jewelers, gemologists, appraisers, and diamond buyers. Engineered for professional efficiency, SAM offers one of the fastest startup and testing times in the industry. It accurately tests gemstones from 0.01 to 10 carats and supports both loose and mounted stones. Designed for portability and convenience, the unit performs approximately 2,000 continuous tests and can be powered via USB or 3 AAA alkaline batteries. The bright LED display ensures easy reading, while the included metal stone rest enhances stability during testing. Whether you are verifying inventory, evaluating purchases, or providing customer assurance, the Presidium SAM delivers speed, precision, and confidence in diamond authentication.
