Which term is the process of forming the basic face-up outline of a diamond to prepare it for faceting?

• A. Brilliant cut
• B. Burn Marks (Brn)
• C. Cavity (Cv)
• D. Bruting

Answer: (D)

Bruting is the step that shapes a rough diamond into its basic face-up outline, creating the round girdle that serves as the foundation for all the facets to come. By rubbing the stone against another diamond (or using a wheel), the edges are worn smooth and the circumference becomes even, establishing the silhouette needed before the precise facet angles are cut. This distinguishes bruting from other terms: the final pattern of facets is the brilliant cut, while burn marks and cavities are defects, not shaping steps.
