What does the term Naif refer to in rough-diamond terminology?

• A. The natural, unpolished surface of a rough diamond.
• B. The surface near girdle after cut
• C. A synthetic diamond variant
• D. A type of diamond deposit

Answer: (A)

Naif refers to the natural, unpolished surface of a rough diamond. This term identifies the stone’s exterior as it exists before any cutting or polishing, showing the original skin and natural irregularities of the crystal. Recognizing the Naif helps a cutter anticipate how much material will need to be removed to create facets, estimate yield, and judge how the stone’s surface quality will influence future polishing. It’s not describing a surface formed after cutting, nor a synthetic diamond variant, nor a geological deposit type, which is why it matches the idea of the natural, unpolished surface of the rough.
