Types and Grading of Natural Colored Diamonds

Natural colored diamonds, also known as fancy colored diamonds, come in various hues such as pink, blue, yellow, and green. These colors are a result of the presence of chemical impurities or structural anomalies during the diamond's formation process. Natural colored diamonds are graded by the Gemological Institute of America (GIA):
  • Color: The most crucial aspect of grading natural colored diamonds. Graded based on three main components: hue (the actual color), tone (lightness or darkness), and saturation (color intensity). The Gemological Institute of America (GIA) grades colored diamonds on a scale ranging from Faint to Fancy Deep, depending on the intensity of the color.
  • Hue: Refers to the diamond’s basic color (e.g., blue, pink, yellow). Some diamonds may exhibit a secondary hue, influencing the final grading.
  • Tone: Assesses how light or dark the color of the diamond appears.
  • Saturation: Evaluates the strength or weakness of the color. Higher saturation generally contributes to a higher value.
  • Carat Weight: Like colorless diamonds, the weight of the diamond is measured in carats. Larger colored diamonds are rarer and typically more valuable.
  • Cut: Refers to how well the diamond has been cut, affecting its overall appearance and brilliance. For colored diamonds, the cut should enhance the natural color.
  • Clarity: Assesses the presence of internal or external flaws. Less emphasis is placed on clarity for colored diamonds compared to colorless ones, as inclusions can sometimes contribute to the color.
  • Distribution: Evaluates how evenly the color is spread throughout the diamond. Uneven distribution can negatively affect the diamond’s grade and value.
  • Rarity and Value: Natural colored diamonds are rare, and certain colors are more scarce and valuable. The grading of the diamond directly influences its market value.
  • Grading Report: Reputable labs like the GIA provide grading reports detailing the characteristics and grade of the diamond. These reports are essential for authentication and evaluation purposes.
