To address concerns about laboratory-grown and treated diamonds being mixed into parcels of melee, GIA has developed an automated system to analyze and sort melee-size diamonds quickly and accurately.

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

Now you can know with confidence that the diamonds in your supply chain are natural.
