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

The Presidium Multi Tester III (PMuT III) is the all-in-one instrument that reliably and accurately verifies the authenticity of colorless diamonds against moissanites and other diamond simulants such as colorless sapphire, colorless spinel, cubic zirconia, zircon, etc. Showcasing a new ergonomic design with a rubberized anti-slip grip and an all-around display for easy readability, PMuT III promises greater ease of handling and reading of results whilst testing.

Presidium’s Multi Tester was the world’s first tester that tests for both colorless diamonds and moissanites in a single instrument. Its measuring probes and electronics circuitry detect data from the gemstone being tested via a customized micro-controller, identifying colorless diamonds and moissanites based on their thermal and electrical properties.

PMuT III has a retractable probe tip that ensures consistent pressure against the gemstone during testing for more reliable results. With the industry’s thinnest probe tip size of 0.6mm, the PMuT III tests colorless diamonds as small as 0.02ct.
