Finalmente un po' di chiarezza e trasparenza sul diamante sintetico e sulle differenze rispetto ai diamanti naturali.
As announced earlier this year, GIA will launch revised evaluation services for D-to-Z laboratory-grown diamonds. 💎 The GIA Laboratory-Grown Diamond Quality Assessment will use descriptive terms rather than the GIA-developed nomenclature for natural diamonds. The laboratory-grown diamonds will be described as ‘Premium’ or ‘Standard’ based on an overall assessment of their clarity, color and cut.
“Using descriptive terms for the quality of laboratory-grown diamonds is appropriate as most fall into a very narrow range of color and clarity,” said Pritesh Patel, GIA president and CEO. “Because of that, GIA will no longer use the nomenclature created for natural diamonds to describe what is a manufactured product.”
This new service will be available on October 1. Current GIA laboratory services for D-to-Z color laboratory-grown diamonds will be available until September 30.
