Which term refers to the outward curve of the pavilion facets of a step-cut diamond?

• A. Pavilion angle
• B. Pattern
• C. Pavilion bulge
• D. Pavilion depth percentage

Answer: (C)

In a step-cut (emerald-cut) diamond, the term pavilion bulge describes the outward curve of the pavilion facets. The pavilion is the lower portion of the diamond, and when its facets curve outward from the girdle, you see a bulging side profile—that curvature is the bulge. This idea is distinct from the pavilion angle (the steepness of those facets), the overall facet pattern, or the depth percentage (how deep the stone is from table to culet). The bulge helps define the stone’s side silhouette and how light dances through the lower part of the diamond.
