Which term refers to placing the first 17 or 18 facets on a diamond?

• A. Bearded Girdle
• B. Belly
• C. Blocking
• D. Brightness

Answer: (C)

Blocking is the stage in diamond cutting where the cutter places the first 17 or 18 facets to establish the basic geometry of the stone. This initial setup defines the table, crown, and pavilion outlines and ensures the culet aligns with the girdle. Getting these facets arranged correctly sets the proportions and symmetry the rest of the facets will refine, and it directly influences how evenly light is reflected and refracted through the finished diamond. After blocking, the cutter proceeds to the final polishing to achieve precise angles and a balanced overall appearance. The other terms describe features or outcomes rather than this initial facet arrangement step.
