Modified Cut Engagement Rings

A modified brilliant cut diamond is a gemstone that utilizes the primary facet arrangement of a traditional round brilliant stone but alters its perimeter shape. Rather than reinventing the optical blueprint, lapidaries preserve the standard triangular and kite-shaped facet structures across the stone's upper crown and lower pavilion. This preservation ensures that non-round silhouettes still maximize light return, fire, and multi-directional scintillation.

A modified brilliant cut diamond is a gemstone that utilizes the essential facet architecture of a classic round brilliant stone but alters its outer perimeter. Instead of throwing out the mathematical optical blueprint that maximizes light performance, master diamond cutters preserve the foundational triangular and kite-shaped facets across the stone's upper crown and lower pavilion. This specialized engineering ensures that non-round silhouettes still deliver exceptional fire, white light return, and multi-directional scintillation.

The primary distinction lies in facet geometry, size, and layout symmetry. A standard round brilliant features a highly predictable pattern of 57 or 58 facets cut to exact angles.

Conversely, modified variants adjust the sizes and positions of these facets to prevent structural vulnerabilities along elongated edges or sharp tips. For example, a cushion modified brilliant may incorporate extra tiers of micro-faceting near the girdle, which generates a twinkling, highly active "crushed ice" visual texture rather than the broad, slower flashes of light seen in a traditional cut.
