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.

Around 99% of colourless and near colourless stones will pass and require no further examination. The AMS2 will refer for further tests all synthetics and simulants and less than 1% of natural diamonds. These referred stones can then be looked at on the DiamondView.

The AMS2 instrument measures approximately 315mm (w) x 400mm (d) x 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.
