Which term describes a person who studies the diamond rough, develops cutting plans, and marks the plans on the rough?

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

Answer: (D)

Planning the cut is the stage where a professional studies the rough, determines the best orientation and sequence of facets to maximize value, and marks those guidelines directly onto the rough. This is precisely what the planner does: analyze the stone and lay out the cutting plan so the cutter can follow it during sawing and faceting. The other terms refer to different roles or steps—polishing is the final finishing of facets, a dop is the tool used to hold the stone during cutting, and bruting is the process of shaping the diamond into a round form. Hence, the person who studies the rough, develops the cutting plan, and marks the plan on the rough is the planner.
