How are simulants' girdles sometimes textured to mimic bruted diamonds?

• A. Wax-like texture
• B. Striations
• C. Mirror polish
• D. Random pits

Answer: (B)

Simulants' girdles are textured with striations to mimic the bruted finish. Bruting roughs the girdle to create fine, parallel grooves around the circumference, giving a frosted, matte appearance rather than a smooth, polished shine. These linear marks—striae—produce the characteristic look of a bruted surface. Other options wouldn’t reproduce that specific, uniform, groove-filled texture: a wax-like feel wouldn’t capture the grooved surface, mirror polish would look too smooth and reflective, and random pits would appear irregular rather than the consistent striated pattern.
