GIA Diamond Grading Guide

The GIA Diamond Grading Guide is a standardized system used to evaluate and communicate a diamond's unique qualities. It assesses four key aspects: Carat Weight (size), Cut (quality of how it’s shaped), Color (absence of hue), and Clarity (internal and external imperfections). These are known as the "Four Cs." GIA's grading reports provide an objective, trusted evaluation, helping buyers understand a diamond's true value and select stones with confidence. The guide ensures consistency in how diamonds are described and compared across the industry.
