Which term describes a weight-retention method that adjusts the angles of some facets to allow portions of a diamond's girdle to be thicker?

• A. Weight retention
• B. Girdle thickening
• C. Painting
• D. Facet angling

Answer: (C)

Weight retention in diamond cutting hinges on how mass is distributed as the stone is shaped. By tweaking the angles of specific facets, a cutter can shift where material remains, allowing the girdle region to be thicker in places while still finishing a balanced, well-proportioned gem. The term described here conveys that idea of deliberately “applying” more girdle thickness through controlled facet adjustments, rather than just removing material or changing overall shape. In this sense, painting captures the notion of guiding the girdle’s thickness by precise facet angling to preserve weight.
