GIA Sees Rise In Synthetics Fraud

The Gemological Institute of America (GIA) is seeing a rise in submission of lab-grown diamonds with counterfeit inscriptions that make the diamonds appear natural. These diamonds have falsified girdle engravings that reference a genuine natural diamond report number, while most have almost identical measurements and weights to the natural diamonds they mimic. Consumers beware.
