Press Release: Jonathan Kendall, the president of the International Institute of Diamond Grading & Research (IIDGR) is pleased to announce that the Automated Melee Screening (AMS) instrument is now being dispatched to De Beers sightholders  across the globe, with the first installation and training sessions having successfully taken place at the end of June with Tasaki and Rosy Blue in Jmelee screeningapan.

Focus has now shifted to installing the AMS in sightholder facilities across key diamond trading hubs such as Antwerp, Mumbai, Hong Kong and Tel Aviv. This is a phased roll out with IIDGR technicians working in parallel in different locations to ensure timely yet comprehensive installation and training. The AMS is the result of several years of development, exhaustive testing and production. De Beers is committed to sustaining trust in diamonds, supporting sightholders and the wider diamond industry, which employs more than 1 million people globally.

Background on the AMS instrument

•• The AMS instrument measures approximately: 42cm deep; 26cm in width; 23cm high. It can be located in any type of environmentally controlled facility and operates as a single machine or multiple units.

•• It screens near-colorless and colorless round brilliant diamonds from 0.20-carats down to 0.01 carat (roughly 1.4mm diameter) to determine whether they are natural or not. The AMS instrument does not screen for treated natural diamonds.

•• The instrument is fully automated and will take up to 500 carats at any one time. Larger parcels may be split across multiple machines.

•• The instrument can be run unattended overnight.

•• The throughput of each instrument is approximately 360 stones per hour.

•• Each instrument is controlled by a compact computer, which is supplied with the machine.
