Part of speech: noun
Definition: Grading in the jewelry industry is a critical assessment method used to determine the value and quality of gemstones, including diamonds. This process relies on standardized criteria known as the 4Cs: Color, Clarity, Cut, and Carat Weight. Color grading involves evaluating the presence or absence of color in a stone, with the most valued diamonds being completely colorless. Clarity grading assesses the gemstone for inclusions or blemishes that can affect its transparency and overall appearance. Cut grading evaluates the stone's proportions, symmetry, and polish, which influence its brilliance and sparkle. Lastly, carat weight measures the size of the gemstone. Together, these factors provide a comprehensive overview of a stone's quality, aiding in its valuation and comparison across the market.
