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.
SAM is the latest technological advancement in handheld diamond & moissanite testers by Presidium that reliable and accurately verifies the authenticity of colorless diamonds, as small as 0.01 carats, against a wider range of moissanites from various countries and other diamond simulants through a higher resolution of thermal and electrical conductivity. Showcasing a sleek chrome brushed ergonomic grip and dynamic micro LED display, SAM ensures ease of usability and distinctly clear result display while testing.
With the industry’s fastest start-up and testing time, SAM only utilizes technology that does not compromise user safety that does not require harmful Ultraviolet (UV) light.
