1
Angle dictates brilliance
Every facet at 34.5° crown and 40.75° pavilion returns light without leakage.
2
Symmetry compounds across 58 facets
A deviation of 0.2° at the girdle propagates to visible dead zones at the table.
3
Proportion is not negotiable
Table-to-diameter ratios outside 53–58% sacrifice either fire or brilliance — never both.
4
Polish grade seals the light path
Surface roughness below 0.05µm Ra ensures total internal reflection at every bounce.
