Our Products
Our Complete range of products are Presidium Screener II, Black Diamond CVD And Moissanite Tester, Diamond Color Master Set, Diamond Sieves and Black Presidium Mate-A Diamond Tester.
The Synthetic Diamond Screener II is developed by Presidium to help screen out Type IIa colorless diamond, which is likely to be laboratory-grown and created through chemical vapor deposition (CVD) or high-pressure high temperature (HPHT) syntheses, from the natural Type Ia colorless diamond.
When subjected to this deep UV irradiation, Type Ia and Type IIa diamonds each absorb different amount of UV light. Type IIa diamonds allow deeper UV light to pass through and thus its UV light absorption ability is low. This difference in light absorption is significant enough to aid in differentiating between colorless Type Ia and Type IIa diamonds.

The Presidium Multi Tester III (PMuT III) is the all-in-one instrument that reliably and accurately verifies the authenticity of colorless diamonds against moissanite 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 moissanite 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 moissanite 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.

The LAPIS is the one and only rechargeable multi-tester you need to distinguish between diamond, moissanite, simulant, and metal. It features a unique ATC Solution (Ambient Temperature Compensation) which will make adjustments in accordance with the ambient temperature change to maintain its accuracy. This overcomes the shortcoming that many testers have, where the temperature of the stone affects the accuracy of the tester.
