Our refractometer is the core instrument we recommend for anyone serious about gemstone identification. It allows you to measure refractive index quickly and reliably, helping you distinguish between look-alike stones and confirm what you have on your desk.

Each unit is calibrated before dispatch and supplied with contact liquid, giving you a ready-to-use setup for the lab, classroom, or workshop. Clear scale markings and a bright, readable display make it practical even during long testing sessions. As working gemologists, we are happy to advise on technique, care, and how to combine the refractometer with other gem testing equipment such as loupes, spectroscopes, and polariscope for more confident conclusions.
