GIA Scale
The GIA Scale (Gemological Institute of America Scale) is the worldwide standard system used to grade and evaluate diamonds. Think of it as a report card for diamonds that helps determine their value and quality. It uses the famous "4 Cs" - Cut, Color, Clarity, and Carat weight. When someone mentions the GIA Scale in their resume, they're indicating they understand how to assess diamonds using this internationally recognized standard. It's similar to having a universal language for describing diamond quality that everyone in the industry understands and trusts.
