The world’s first diamond and moissanite tester with a replaceable tip, and a micro probe tip to authenticate diamonds as small as 0.01 carats.

Pocket-sized instrument that instantly verifies the authenticity of diamonds based on their thermal properties.

Handheld tester that instantly distinguishes moissanites (a diamond simulant) from genuine diamonds, based on electrical properties.

Convenient all-in-one handheld instrument that instantly separates diamonds from moissanites and other diamond simulants, based on their thermal and electrical properties.

Enhanced with additional features, the Synthetic Diamond Screener II now tests for diamond melees as small as 0.02 carats with instantaneous results, through the measurement of UV absorption.

The only gemological instrument in the industry that tests gemstones using both thermal and reflectivity testing.

The only handheld digital tester in the industry specifically for colored gemstones, and tests for 31 types of gemstones.

The first desktop instrument that estimates colored gemstones and identifies diamonds, using the principle of thermal properties of gemstones.

Desktop digital tester that uses refractive index to quickly separate gemstones, diamonds, moissanites and other diamond simulants.

Instantaneously identifies synthetic rubies through its high UV transmittance.

The industry’s only easy-to-use analog gauge for measuring gemstone dimensions with direct conversion to carat weight for round brilliant-cut diamonds.

The industry’s most reliable digital gauge that measures gemstone dimensions with direct conversion to carat weight for round brilliant-cut diamonds.

An advanced digital computer gauge that measures gemstone dimensions and can estimate gemstone weight and identity for 9 different cuts.
