PRESIDIUM DIAMOND VERIFICATION INSTRUMENT™

ARI by Presidium


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.



Features

  • User-safe UV Retractable Optical Probe activates only when tip is in contact with the diamond
  • Alert Buzzer for loss of contact between optical probe tip and diamond during testing
  • A 6-Language selection in the Graphic User Interface (GUI)
  • Battery operated with stylish ergonomic design for portability and ease of use
  • Tests on colourless diamonds and moissanites from D to J colour
  • Catered for both left-handed and right-handed users alike

Benefits

  • Identifies colourless diamonds against Lab Grown CVD/HPHT diamonds and all types of moissanites, including the new “low conductivity” moissanites
  • Tests on loose or mounted diamonds in all jewelry settings, including closed-back setting
  • Replaceable Optical Probe tip technology for users to replace any worn or damaged probe tips yourself, minimizing any equipment downtime
  • Instantaneous results in 3 seconds for consecutive testing
  • Tests on polished diamonds and moissanites of all proportional cuts as small as 0.02ct
