Diamond & Moissanite Testers

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.

Developed by Presidium to identify diamonds against a wider range of moissanites, including the new “low conductivity moissanite”, and other diamond simulants through its highly sensitive thermoelectrical probe.
