GIA Taking Submissions For Melee Analysis Service Following Successful Trial

The Gemological Institute of America (GIA) on December 5 published the following press release: Following a five-month pilot program which started in June 2016, clients are now able to submit round D-to-Z melee-size diamonds through their fully automated GIA Melee Analysis Service. The fully automated system rapidly and accurately analyzes and sorts diamonds ranging from 0.90 to 4.00 mm in diameter (approximately 0.005 ct to about 0.25 ct.), was developed in response to the trade’s concerns regarding the possibility of synthetic or treated diamonds being mixed into parcels of melee. The service is currently offered at most GIA laboratories.

The GIA Melee Analysis Service separates natural, untreated diamonds from simulants and potentially synthetic or treated diamonds, and sorts the screened diamonds by color range. Clients are also able to specify a size range for their parcel. The system is able to examine treated and synthetic diamonds, and processes an average of 1,800 to 2,000 stones per hour. The service cost ranges from eight to 40 cents (U.S.) per stone based on diameter, with a minimum of 500 pieces in each parcel. Once sorted, the melee will be sealed in secure packaging for shipment which upon request can be sent directly to a third party, or back to the submitting client.
