The Cushion Cut diamond commands attention with amazing Brilliance and extraordinary Dispersion or Fire emanating from a large pillow-like Crown.

Cushion cut diamonds are square to rectangular with rounded corners. The right shape depends entirely upon your personal preferences.

The Cushion Cut was developed toward the end of the 19th century with the intent to create a diamond whose Brilliance, Fire and Scintillation would be unrivaled in candlelight.
