ARI by Presidium is an advanced, handheld diamond verification tool designed to accurately identify natural diamonds, CVD/HPHT lab-grown diamonds, and all types of moissanites, including the latest low-conductivity moissanites. Using proprietary UV light absorbance technology, ARI provides precise, reliable results in as little as 3 seconds, making it the perfect solution for jewelers, gemologists, and anyone in need of diamond verification.
With its user-friendly touch screen colour LCD display and ergonomic design, ARI is easy to operate and suitable for both left- and right-handed users. The tester works on loose or mounted diamonds, including those in closed-back settings, and can test diamonds as small as 0.02ct. It also supports 6 languages in its graphic user interface (GUI), making it accessible to a global market.
ARI is powered by 3 AAA alkaline batteries (offering up to 4 hours of continuous use) or an AC adapter, making it portable and convenient for on-the-go testing. The replaceable optical probe tip minimizes downtime, ensuring you can continue your work without interruption. Whether you're in a jewelry store or a lab, ARI delivers accurate results with every test.
