  • ❤ Jewelry Tester Identification Tool: The data gemstone refractometer is composed of high-sensitivity sensors and LCD screens.It can measure the refractive index value of gemstones non-destructively, quickly and accurately, and can determine other optical characteristics of gemstones. Measuring range: refractive index 1.300-3.000.a measurement accuracy of up to 0.001, a measurement error of ±0.005.
  • ❤ Working Principle: Operating on the basis of total internal reflection, the gemstone tester measures one of the most fundamental optical parameters of gemstones—the refractive index. This key characteristic allows users to accurately identify and differentiate gem types based on their unique optical properties.
  • ❤ Test Method: Unlike traditional methods, this gem Identification Instrument requires no refractive oil. Simply place the sample’s measurement close to the platform for instant results. The process not only simplifies working but also maintains the integrity of delicate gems.
  • ❤ Clear Visual Reading: Featuring a large LCD screen with backlight illumination, a high-sensitivity sensor, and intelligent electronics, the device ensures excellent readability even in low-light conditions. Powered by a rechargeable 700mAh lithium battery, it supports up to 10,000 measurements per charge.
  • ❤ Wide Applications: Gemstone ldentification Tester Quickly and accurately identify single and double gemstones, moissanite/diamonds/colored gemstones/crystals, designed for measuring the refractive index of gemstones and solid materials. widely used in gem jewelry stores, etc.
