Study Notes
Diamond Color Grading
- Characteristic Color: The basic visible color of a diamond.
- Depth of Color: The combination of tone and saturation of a diamond.
- Hue: The initial impression of diamond color.
- Master-Eye Effect: The optical illusion causing diamonds to appear lighter or darker compared to masterstones.
- Masterstones: A set of color-comparison diamonds that define GIA diamond color grades (D-to-Z).
- Saturation: The intensity of a diamond's color.
- Tone: The darkness or lightness of a diamond's color.
Key Concepts
- Slight color differences can significantly affect value.
- Color is described by hue, tone, and saturation.
- Low saturation colors appear grayish or brownish.
- GIA color grading is the industry standard.
- Each letter grade (e.g., D, E) represents a narrow color range with the least amount of color in each step.
- The biggest price difference is between D and E grades.
- Color grading should occur in a controlled environment with balanced or daylight-equivalent lighting.
- Matching masterstones to specific grading requirements and maintaining clean conditions for the diamonds and masterstones are crucial for accurate results.
- Cut, size, and clarity can also impact perceived color.
- The goal is repeatable and consistent color grading.
