Which characteristics represent poor value because they appear smaller face-up?

• A. Thick girdle, steep crowns, or deep pavilions represent poor value because they appear smaller face-up than their weights suggest.
• B. Very thin girdle with shallow crown.
• C. Thick girdle, steep crown, or deep pavilion.
• D. Large culet helps weight.

Answer: (C)

Understanding how proportions affect how large a diamond looks face-up is essential. When the girdle is thick, the crown is steep, or the pavilion is deep, more of the weight sits below the crown and pavilion rather than contributing to the visible diameter you see from the top. That means the stone can weigh more (in carats) but appear smaller face-up, which consumers perceive as poorer value because they’re paying for size that isn’t visually present. So, the combination of a thick girdle with a steep crown or a deep pavilion directly leads to a reduced face-up size for the given weight, making it poorer value. In contrast, a very thin girdle with a shallow crown tends to maximize face-up size for the same weight, improving perceived size and value. A large culet adds weight but doesn’t improve how large the diamond looks face-up, so it doesn’t address the same value concern.
