Ideal cut diamond (with the right proportions). A Round Brilliant diamond is cut with 58 flat faces total. The size, placement, and symmetry of the facets impact how well the diamond refracts and reflects light.

Modeled in Blender 2.93. Scale 1 m, if you need a stone such as 3 carats you need a scale of 0.009 m. Cycles don't support dispersion so I rendered in Arnold. Diamond IOR : 2.418

Three variants of the model:
- Highpoly
- Subdivision level 0. Bevel 0.00001 m
- Subdivision level 0. Bevel 0.0001 m (Bevel are executed by a modifier which is not applied in the Blender project file, you can change values)
