With practice, table size estimation techniques can be described as?

• A. Quick and fairly accurate.
• B. Very time-consuming.
• C. Only possible with specialized equipment.
• D. Always exact.

Answer: (A)

Estimating table size becomes a fast, reliable judgment with practice because you learn to use simple visual references on the stone to gauge how much of the overall diameter the table occupies. By comparing the table edge to the girdle and to surrounding facets, you develop a sense for the table’s percentage of diameter without needing precise tools. This approach yields a quick, fairly accurate estimate useful for quick screening and initial evaluation. It isn’t always exact, and it doesn’t require specialized equipment, but accuracy improves markedly with experience.
