Outward curve of the pavilion facets of a step-cut diamond is called what?

• A. Shape Appeal
• B. Pavilion Bulge
• C. Length-to-Width Ratio
• D. Fancy Cut

Answer: (B)

Outward curvature of the pavilion facets on a step-cut diamond is called the pavilion bulge. In emerald/step cuts, the pavilion is the lower half from the girdle to the culet, and the facets there can curve outward, producing a bulging side view. This term specifically describes that curvature and how the bottom of the diamond presents when viewed from the side, which can influence symmetry and how light travels through the pavilion. The other options don’t refer to this specific feature: shape appeal is a general aesthetic idea, length-to-width ratio concerns overall proportions, and fancy cut denotes a category of unusual shapes rather than the curvature of the pavilion.
