The SmartPro Optimum 1 is a portable diamond/moissanite screener that can distinguish natural diamonds from synthetic diamonds and moissanite using reflectivity. It can test for both chemical vapor deposition (CVD) and high-pressure, high-temperature (HPHT) synthetic diamonds. Suitable for use with D to M graded colorless to faint colored stones, the device can screen both mounted and unmounted stones (including those in closed-back settings) measuring from 0.015 carat to 10 carats. Offering nearly instant results, the handheld device can be set up for right-handed or left-handed use. It does not screen cubic zirconia, other simulants, or glass.

Using advanced proprietary technology, the Presidium ARI measures ultraviolet light absorbance to identify colorless diamond against lab-grown diamonds (both chemical vapor deposition [CVD] and high-pressure, high-temperature [HPHT] created stones) as well as all types of moissanite. Suitable for testing on both loose and mounted stones, including those with closed-back settings, the device features a user-safe UV retractable optical probe that activates only when the tip is in contact with the stone; an alert buzzer will go off when contact is lost during testing. Powered by three AAA batteries or an included adapter, the tester can be used on colorless diamonds and moissanites from D to J color. Test results are provided within three seconds of testing. It measures 7.5 inches long by 1.8 inches wide by 0.9 inch high (190 mm by 46 mm by 25 mm) and weighs 0.13 lb. (without batteries). Contact: A&A Jewelry Supply, 319 W.
