diamond grading standards

Diamond grading standards assess a stone’s quality based on the "Four Cs": Carat (size/weight), Color (how colorless it is), Clarity (internal flaws and inclusions), and Cut (how well it’s shaped and faceted). These factors determine a diamond’s beauty and value. Grading labs assign a grade or scale to each aspect, helping buyers compare and choose with confidence. A well-cut, clear, colorless diamond with appropriate size offers the most brilliance and value. Understanding these standards ensures informed decisions and appreciation of a diamond’s unique characteristics.
