Gem Testers

To amateurs, gemologists, and professional jewelers alike, the process of identifying gemstones, especially in large quantities, is a difficult and tedious one. To complicate things even further, new varieties of simulants designed to mimic the properties of gems are constantly being developed. So how does one save themselves the time, effort, and cost of mistakes associated with confusing a simulant for a true precious stone? The answer is simple: with an electronic gemstone tester. Electronic gem testers test the physical properties of stones, which are significantly more distinct and difficult to falsify than physical appearance can be, making them both precise and accurate.

We carry a full line of products from Presidium Instruments, as well as Gemlogis, two of the finest manufacturers of electronic jewelry testing equipment, and specifically, electronic gemstone testers.
