Which term describes very small feathers that extend from the girdle surface into the stone, and can result from the cutting process?

• A. Bearded Girdle
• B. Belly
• C. Beneficiation
• D. Best Practices Principles

Answer: (A)

Bearded girdle describes very small feathers that extend from the girdle surface into the stone. These fine, hair‑like extensions form when the diamond is cut and the girdle edge is finished, leaving micro-feathers that poke into the stone. This is directly tied to the cutting process, which is why this term fits the description. The other terms don’t describe a girdle-related feathering phenomenon—belly isn’t about bearding, beneficiation is ore processing, and best practices principles are general guidelines rather than diamond anatomy.
