Cushion Cut
The cushion cut — a square with softly rounded corners, like a pillow — is one of the oldest and most romantic gemstone shapes, descended from the antique old mine cut.
What is a cushion cut?
A cushion cut is square or rectangular with gently rounded corners, giving a soft, pillow-like outline. It suits both diamonds and coloured stones such as sapphire, ruby and emerald, and its larger facets give a warm, watery brilliance.
History & why it matters
The cushion cut descends directly from the hand-cut old mine cut and has been used for centuries. Antique cushion-cut stones are prized for their character and are a favourite for engagement rings.
What affects value
For diamonds, the 4Cs apply, but with antique stones the cut and period setting add value. For coloured stones, colour leads. Browse antique gemstone jewellery or read about gemstone cuts.
