Gemstone Testers

Using thermal conductivity and reflectivity, gemstone testers from such notable companies as Presidium, Gemlogis, and SmartPro can help distinguish between many of the more common gemstones you may come across in your jewelry buying and jewelry appraisal businesses. Gemstone Testers are not guaranteed to tell you exactly what you have, however many users find them to be a valuable addition to their gemological toolbox.
