Automated Melee
Testing (AMS2)

The new AMS2 instrument represents a significant technological advance in the field of diamond melee screening. A product of De Beers world-leading expertise in diamond research, a revolutionary measurement technique gives a much lower referral rate than its predecessor.

Operating at a much higher speed, the AMS2 instrument accepts a wider range of stone sizes and shapes with smaller minimum sizes, yet is available at a lower cost compared to the previous generation AMS device.

The AMS2 will refer for further tests all synthetics and simulants and less than 0.5% of natural diamonds. These referred stones can then be looked at on the DiamondView.

The AMS2 instrument measures approximately 315mm (w), 400mm (d) and 550mm (h). The machine can be located in any type of environmentally controlled facility. The instrument has a fully embedded system; no external PC is required.
