Which term describes a portion of the original rough diamond surface that is left on the finished stone, typically near the girdle?

• A. Naif
• B. Natural (N)
• C. Master-eye effect
• D. Matching tray

Answer: (B)

In diamond terminology, a Natural refers to a portion of the original rough diamond surface that is left on the finished stone, typically near the girdle. This is an intentional retention of the crystal’s natural skin after the cutting process, rather than a completely polished surface. It preserves weight and preserves a record of the rough origin, often appearing as a small, irregular patch or edge along the girdle. That’s why this term is the best choice: it specifically describes a natural fragment of the rough surface still visible on the finished diamond, which matches the described placement. The other terms don’t apply to surface features left from the rough; they refer to different concepts or features unrelated to this particular girdle-area surface retention.
