IIDGR Displays New AMSD in Greater China

Automated Melee Screening (AMS) machine inaugurated by GIIHong Kong: The De Beers Group of Companies’ International Institute of Diamond Grading & Research (IIDGR) showcased the new Automated Melee Screening (AMS) device to great reception at this September’s Shenzhen International Jewellery Fair and Hong Kong Jewellery & Gem Fair.

The new AMS device which can take up to 500 carats at once is a spectrometer based system that screens round brilliant diamonds from 0.01 – 0.2cts for potential synthetics and simulants. It automatically feeds, measures and dispenses at a rate of 360 stones per hour and is the result of several years of development, exhaustive testing and production. The device has already been installed successfully across key worldwide diamond trading hubs to increase trade and consumer confidence in this category of diamond.

Jonathan Kendall, President of The IIDGR, commented: “The De Beers Group of Companies is committed to sustaining trust in diamonds across the industry. It is essential that all synthetics and simulants are fully disclosed to ensure confidence and transparency is maintained within the trade. The AMS device, the latest instrument to be developed by De Beers is able to aid in this assurance by screening melee and detecting all synthetics and simulants tested.”

The IIDGR also promoted responsible practices in diamond grading at the two fairs and demonstrated the Institute’s other proprietary detection instruments:

  • DiamondSureTM –  a screening device to determine natural 0.10-10 carat diamonds from synthetics and simulants.
  • DiamondViewTM – a desktop based device designed to look at any stones that have been referred by DiamondSure™.
  • DiamondPlusTM – a device that screens for type II HPHT treated natural diamonds and CVD synthetics.

Jonathan Kendall added, “We are the leading manufacturers of detection instruments for the diamond industry. Our proprietary equipment is used as the de-facto standard by government agencies, gemmology laboratories, Diamantaires, jewellery manufacturers and jewellery retailers all over the world.”
