Which term refers to a holder that secures a diamond during processing?

• A. Bruting
• B. Coning
• C. Polishing
• D. Dop

Answer: (D)

In diamond processing, the holder used to secure the diamond is called a dop. A dop is a small pin or stem that the stone is attached to—often with wax or adhesive—so the diamond can be rotated and precisely oriented while grinding, shaping, and polishing each facet. This secure mounting is essential for maintaining accurate angles and symmetry throughout the faceting process. The other terms describe processing steps rather than the holding device: bruting shapes the stone into a round outline, polishing finishes the facets, and coning refers to a shaping step rather than a holder.
