Which statement about table size measurement is true?

• A. Measure the table facet in four directions and average.
• B. Take a rough guess based on stone size.
• C. Measure the table in two directions and multiply.
• D. Estimate the table size visually without measurement.

Answer: (D)

Table size refers to the diameter of the diamond’s table facet, and in practice you want to know this dimension accurately because it affects symmetry and overall cut quality. While precise determination uses calipers and a measured approach, the statement that is true in a quick, practical sense is that you can form a rough sense of the table size by eye before measuring. A trained eye can visually assess whether the table appears proportionate and if it looks unusually large or small, which is useful as a preliminary check. The other methods described—measuring in multiple directions and averaging is more precise work, multiplying two directional measurements, or guessing purely from stone size—don’t reflect how table diameter is defined or reliably determined for grading.
