A table facet is the flat top surface of a cut diamond - imagine it as the "window" you look through to see into the diamond. It's one of the most important parts of a diamond's cut because it's the largest flat surface that lets light enter and exit the stone. Diamond cutters and graders pay special attention to this feature because its size and quality greatly affect how sparkly and valuable the diamond will be. The term "table" is used regularly in jewelry workshops and diamond grading reports, and you might also hear it called the "table surface" or "crown table."

Q: How do you determine the optimal table facet size for different diamond shapes?
Expected Answer: A senior diamond cutter should explain how they consider the rough diamond's shape, desired final weight, and target market preferences. They should mention how table percentages vary between different shapes (round, princess, oval) and how they balance this with achieving maximum brilliance.
Q: What methods do you use to ensure precise table facet alignment?
Expected Answer: They should describe their quality control process, including use of measuring tools, optical verification methods, and how they train others to maintain consistency in table alignment across different diamond cuts.
Q: What are the acceptable table percentage ranges for round brilliant diamonds?
Expected Answer: Should demonstrate knowledge of industry standards for table percentages (typically 53-58% for round brilliants) and explain how this affects diamond appearance and value.
Q: How do you handle a situation where the table facet is slightly off-center?
Expected Answer: Should explain the assessment process, correction techniques, and when it's appropriate to adjust versus when to consider alternative cutting solutions.
Q: What is a table facet and why is it important?
Expected Answer: Should be able to explain that it's the top flat surface of the diamond and describe its basic role in light performance and overall diamond appearance.
Q: What basic tools do you use to measure table facet percentage?
Expected Answer: Should be familiar with basic measuring tools and demonstrate understanding of how to calculate table percentage using simple measurements.
