Which term describes a small diamond used to kerf another diamond or round up a girdle during polishing?

• A. Dopping Stone
• B. Sharp
• C. Girdle Polisher
• D. Table Cutter

Answer: (B)

In polishing, tiny diamonds are used as abrasives to shape edges and facets. A sharp refers to a very small diamond worn as an abrasive, ideal for kerfing a diamond (making precise grooves) or rounding up the girdle edge. Its small size and pointed edge let it remove just enough material with control, which is exactly what you need for delicate edge work. The other terms describe tools for mounting or specific surface work (a dopping stone to attach the diamond to a dop stick, a girdle polisher to smooth the girdle, and a table cutter for the table facet), not the abrasive used for kerfing or girdle refinement.
