The AMSMicro (Automated Melee Screening Micro) is an automated melee screening instrument for diamonds from 0.001ct to 0.0033ct (0.60mm to 0.90mm). It is designed to screen large quantities of loose, colourless and near colourless, round-brilliant melee, with speeds of up to 2200 diamonds per hour.

The instrument screens and separates diamonds, laboratory grown diamonds and diamond simulants, with a natural diamond referral rate of less than 3%.

As a fully integrated unit with digital touch screen display, screening results are displayed within seconds. With an automated pick and place, measure and dispense process, the AMSMicro can run unattended while no additional expertise is required to operate the instrument, for accurate results.
