Which term describes a clarity characteristic confined to the surface of a polished gemstone?

• A. Blemish
• B. Belly
• C. Brightness
• D. Blocking

Answer: (A)

Surface flaws on a polished gemstone are the focus here. A blemish is an external flaw on the surface of a polished diamond—such as nicks, scratches, pits, or processing marks—that does not extend into the interior. Because these imperfections are confined to the surface, blemishes are the clear term for a surface clarity characteristic. The other options don’t describe surface flaws: brightness relates to light performance, while belly and blocking aren’t standard terms for surface clarity.
