Diamond Screener II

535 OMR
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 Synthetic Diamond Screener II is developed as a portable DIAMOND VERIFICATION INSTRUMENT 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 all diamonds allow deeper UV light to pass through and thus its UV light absorption ability is low. This difference in the light absorption is significant enough to aid in differentiating between colorless Type Ia and Type IIa diamonds.

Ruby Scanner

960 OMR
Instantaneously identifies synthetic rubies through its high UV transmittance. The Ruby Scanner is a ground-breaking desktop device that instantaneously identifies synthetic (flame fusion) rubies through its characteristic high UV transmittance. Utilizes UV light with auto cut-off and gives quick results with clear indicator lights to measure the UV transmittance ability of ruby gemstones. Works on both single mounted stones (with open-back setting) and loose rubies.

Equipped with a precise and slim 0.06 mm probe that ensures precise pressure and sure conductivity on diamonds, for sure results, it can test diamonds of 0.02 carats size.


230 OMR
Convenient all-in-one handheld instrument that instantly separates diamonds from moissanites and other diamond simulants, based on their thermal and electrical properties. SW550DT 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, SW550DT promises greater ease of handling and reading of results whilst testing. SW550DT 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 SW550DT tests colorless diamonds as small as 0.02ct.


290 OMR
The only handheld tester in the industry specifically for colored gemstones, indicates up to 31 different types of colored gemstones based on their thermal conductivity and even features a color input function that allows users to select from a range of 12 common colors, thereby achieving more accurate results. With an easy-to-read clear digital LED screen, this smart thermal tester also comes with the patented refined changeable probe tip, which ensures minimal equipment downtime, This Gem Indicator is an enhanced and more convenient handheld version of the revolutionary Gem Tester/Colored Stone Estimator. This Indicator probe consists of two linked thermometers; one which is heated electronically, while the other is cooled by the gemstone being tested, The difference in temperature creates an electrical output, which is then amplified and displayed on the new digital organic LED display, it is simple to use, easy to maintain and quick in giving you intelligent results about your colored gemstones.
