Marquise Diamonds: The Shape That Looks Biggest Per Carat
The marquise diamond is an elongated shape with two pointed ends, designed to maximize surface area. Carat for carat, it looks larger than almost any other diamond shape and dramatically elongates the finger.
Quick answer: A marquise diamond appears bigger than its carat weight, flatters the hand and often costs less per carat than a round. Watch for symmetry and the bow-tie effect, and protect the two points with V-prongs.
A shape with history
Commissioned in 18th-century France and named for a marquise (a noble rank), this regal cut has a romantic backstory that suits vintage and nature-inspired settings.
Why it looks so large
Its long, narrow outline spreads weight across the top of the stone, giving a generous face-up size. The elongating effect also makes fingers look longer and slimmer.
What to look for
- Symmetry: Both points should align perfectly, or the stone may look crooked when set.
- Bow-tie: Choose a stone where the central shadow is minimal.
- Point protection: V-prongs guard the vulnerable tips.
