Which term describes hazy surface areas that result from excessive heat or from uneven polishing caused by structural irregularities; also called polish marks or burned facets?

• A. Bruise (Br)
• B. Burn Marks (Brn)
• C. Cavity (Cv)
• D. Bruting

Answer: (B)

Haziness on a diamond’s surface caused by overheating during polishing or by uneven polishing from structural irregularities is known as burn marks. This term describes the milky, cloudy patches that scatter light rather than reflecting it cleanly, which dulls brilliance. It’s a surface flaw tied to the finishing process, sometimes also called polish marks or burned facets. Bruise refers to a surface impact damage that can create chips or dents rather than hazy patches. A cavity is a hollow area from internal damage or loss of crystal, not a surface haze. Bruting is the shaping process used to create the round profile, not a defect.
