This preparatory phase encompasses a series of steps aimed at getting the diamond ready for final polishing. It includes pre-forming, to further refine the shape; planning, for finalizing the facet layout; positioning, to align the diamond correctly for faceting; and pre-polishing, to smooth the surface before the final polish. Preparation is critical for setting the stage for the meticulous faceting process. It ensures that the diamond is perfectly shaped and positioned, minimizing flaws and maximizing the stone’s reflective qualities. This stage requires a high level of craftsmanship to ensure the diamond meets stringent quality standards.
