Plot on a GIA grade report refers to what?

• A. A map of a diamond's inclusions, blemishes, and facet arrangement.
• B. A chart showing the distribution of carat weights across a lot.
• C. A diagram of the ideal cut proportions.
• D. A summary of the polishing history.

Answer: (D)

The Plot on a GIA grade report is a diagram that marks where a diamond’s internal inclusions and surface blemishes are located. It provides a visual map of imperfections, which helps determine the clarity and understand how defects may affect how the diamond looks under light. It’s not about polishing history, carat distribution, or an outline of ideal cut proportions, and it doesn’t depict the facet arrangement.
