ARI by Presidium is a handheld diamond and moissanite screener that distinguishes colorless diamonds from CVD/HPHT lab-grown diamonds or moissanites—for loose and mounted stones.
It is suitable for testing on both loose and mounted stones down to 0.01ct, including jewellery pieces with closed back settings.
Through advanced proprietary technology, the ARI measures the UV light absorbance ability of Diamond and Moissanite.
Simply depress the needle against the top surface of a diamond to achieve a clear and accurate reading in just 3 seconds.
Depending on the stone tested, the ARI touchscreen LCD display will show "DIAMOND" CVD/HPHT/TYPE IIA" or "MOISSANITE"
