Which term describes a dark area across the center of an elongated brilliant cut?

• A. Brick-and-mortar retailer
• B. Beneficiation
• C. Blemish
• D. Bow-tie

Answer: (D)

The main idea here is how light performance in elongated brilliant cuts creates a bow-tie pattern. In shapes like marquise or other stretched profiles, the facets can cause light to reflect away from the viewer in the center, producing a darker, cross-shaped area that runs from one tip to the other. This dark central zone is described as a bow-tie, and it’s a known visual effect of the cut, not a surface flaw. The other terms don’t fit: a blemish is a surface flaw, while brick-and-mortar retailer and beneficiation are unrelated concepts. So the elongated brilliant cut showing a dark center is characteristic of a bow-tie.
