Marquise Cut Diamonds: Maximising Apparent Size

The marquise is a long, pointed-oval shape that can make a diamond's carat weight look larger than almost any other cut.

Elongated geometry

With two pointed ends and a wide centre, marquise diamonds maximise length for a given carat weight, often giving the largest visual footprint per carat of any standard shape.

Bow-tie and point protection

Like other elongated shapes, marquises can show a bow-tie shadow, and both pointed tips need protective prongs to resist chipping over years of wear.

Historic origins

The shape is said to date to 18th-century France, where it was reportedly cut to resemble the smile of the Marquise de Pompadour — a charming story, though its exact origin is debated among historians.

Buyer checklist

  • ✓ Check both tips for symmetry and chip protection
  • ✓ View for bow-tie severity under normal lighting
  • ✓ Compare length-to-width ratio to personal preference
