Table Percentage

Table percentage refers to the ratio of the diameter of the top of the diamond compared to its overall diameter, impacting its brilliance and fire.

Part of speech: noun
Definition: Table percentage is a critical factor in evaluating the quality and appearance of a diamond, representing the ratio of the width of the diamond's top facet (known as the table) to the width of the entire stone at its widest point. This key measurement influences how light is refracted within the diamond, thereby affecting its sparkle, brilliance, and fire. Ideal table percentages vary depending on diamond shape, but typically fall within a range that balances brightness with the dispersion of light. A well-proportioned table percentage is crucial for maximizing the visual appeal of a diamond, making it a significant consideration in the selection process. This concept is particularly important for jewelers and gemologists who assess diamonds for jewelry, ensuring that the stones exhibit exceptional beauty and luminosity.
