Which term is a device that holds the dop and allows polishers to adjust and maintain a diamond's angle during polishing?

• A. Tang
• B. Tetrahedron
• C. Thermal conductivity
• D. Surface Graining

Answer: (A)

The tang is the component that secures the dop in the polishing setup and allows precise angle control. It’s the projection on the dop that fits into the holder or clamp, so you can tilt and lock the diamond at the exact angle needed for each facet. A stable tang lets the polisher maintain that angle as polishing progresses, which is critical for achieving accurate facet geometry and symmetry. The other terms aren’t about mounting or adjusting the dop: a tetrahedron refers to a diamond’s crystal shape, thermal conductivity is a material property related to heat transfer, and surface graining describes the finish texture on a surface.
