A gem refractometer is a tool used in the gemstone industry to measure the refractive index of gemstones. This value is a measure of how much light is refracted, or bent, as it passes through the stone. By comparing the measured value to a known index of refraction for that type of gemstone, gemologists can identify the type of stone, as well as determine its authenticity and quality. A gem refractometer is an essential tool for anyone involved in the gemstone industry, providing a quick and accurate way to identify gemstones and ensure customers are getting a genuine and high-quality product.
