This service was first created in 2016 for round brilliant melee diamonds to address concerns about laboratory-grown and treated diamonds being mixed into parcels of melee. GIA has now expanded the automated system to analyze and sort melee-size diamonds that are fancy-shaped.

 The GIA Melee Analysis Service separates natural diamonds from laboratory-grown and potentially HPHT treated natural diamonds for round and fancy-shaped melee along with identifying any simulants. For round melee only, the screened diamonds can be sorted by color range for an additional charge. Clients can also specify a size range to sort for their round melee parcel. Once sorted, the melee will be sealed in secure packaging and retuned.
