ARI by Presidium
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
ARI is developed as a handheld PRESIDIUM DIAMOND VERIFICATION INSTRUMENT® to help identify colourless diamond against CVD/HPHT lab grown colourless diamond and all types of moissanite. It is suitable for testing on both loose and mounted stones, including jewelry pieces with a closed back setting.
Through advanced proprietary technology, ARI measures the UV light absorbance ability of diamond and moissanite. With its touch screen colour LCD display, ARI provides a clear and accurate result of “Diamond”, “CVD/HPHT/Type IIa” and “Moissanite” within 3 seconds.
Product comes with 1-year warranty.
