The round brilliant cut is optimal for displaying garnet brilliance because its 57-58 facet pattern is mathematically designed to maximize light return. The precise angles create internal reflections that direct most light back through the crown, producing exceptional sparkle. For garnets with their high refractive indices, this cut captures and returns more light than any other shape. The symmetrical arrangement of facets also disperses light evenly, minimizing dark areas while creating a perfect balance of brilliance and fire that showcases the stone’s natural beauty.
