Gemstone Refractometer for Jewelry Testing, LCD Screen, Refractive Index 1.300-3.000, Ideal for Diamonds, Gold & Silver Identification Tools

Introducing our Gemstone Refractometer, the essential tool for jewelry enthusiasts and professionals alike. With its large LCD backlight display, this refractometer offers exceptional accuracy, measuring refractive indices from 1.300 to 3.000 with a precision of ±0.005. This device is ideal for identifying a variety of gemstones, including jade, Hetian jade, and diamonds, ensuring you can confidently assess the authenticity and quality of your jewelry. Whether you are a jeweler, a gemologist, or simply an avid collector, our refractometer is designed to enhance your gemstone testing experience. For jade, it determines if the refractive index aligns with the expected value of approximately 1.66, safeguarding your investment in polished pieces. In the case of Hetian jade, it confirms whether the rough stone meets the standard index of around 1.61. This is crucial for anyone looking to verify the quality of their gems before making a purchase or sale. The diamond testing feature is particularly valuable, as it distinguishes between natural and synthetic diamonds. With a refractive index up to 2.417, our refractometer helps you identify genuine diamonds, while also flagging artificial stones with indices ranging between 1.98 and 2.2. Specifications include a measuring range of 1.300-3.000, an impressive battery life supporting up to 10,000 uses, and a compact design with dimensions of 13.5x7.8x2.4 cm (5.31x3.1x0.94 inches) and a lightweight of only 0.8 kg (1.76 lbs). The product comes complete with a calibration block set, an aluminum case for storage, and a user-friendly instruction manual. Enhance your gemstone testing process with our reliable Gemstone Refractometer. If you have any questions or need assistance, our dedicated customer service team is available to respond within 24 hours. Unlock the true potential of your jewelry collection today!
