ELECTRONIC GEMSTONE GAUGES

Gem Gauges are used to perform precise measurements of the gemstones - either to estimate mounted stone carat weight or to check stone cut quality, for appraisals, documentation purposes, even to check ring size. Gauges can be used on mounted or loose stones, in your lab, workshop or just anywhere else. Some gauges require use of tables where you can figure out carat weight of the stone based on your measurements, some more advanced computerized gem gauges are capable to calculate carat weight themselves.
