In diamond terminology, what is a blemish?

Explanation:
Blemish is a surface flaw on a polished diamond, meaning a feature that exists on the exterior rather than inside the stone. Because blemishes are confined to the surface, the description that matches is a surface feature confined to the surface of a polished gemstone. Internal features are called inclusions, and a fracture within would be an internal crack rather than a surface flaw, while a color defect isn’t how blemishes are defined despite any visible effect on appearance.
