Marquise Diamond Engagement Rings
Face-up, a marquise looks bigger than any other diamond of the same weight — the elongated, pointed outline spreads more visible surface per carat than every rival shape. The cut was commissioned in 18th-century France, and jewellers still call it the navette, or "little boat." Our marquise engagement rings run from $768 to $4,368 across 126 designs.

The pointed tips make a marquise diamond ring naturally dramatic: worn north-south in a classic solitaire, ringed by a halo for extra fire, or turned east-west for a contemporary line. A marquise cut diamond also sits beautifully above a curved marquise wedding band shaped to follow its points.
Why choose a lab-grown marquise
Marquise cut diamonds demand exact symmetry — the two points must align perfectly or the whole stone looks off — and lab-grown material makes that precision affordable: identical hardness and fire to mined, IGI-graded, at a fraction per carat.

Marquise diamond proportions and pairing
The reference ratio is 1.85–2.10 — shorter reads plump, longer turns needle-like and fragile-looking. Symmetry is checked in one glance: imagine a line down the centre; the two points must sit exactly on it, and the two halves must mirror. Even a slight tilt of one point is visible at conversation distance, which is why the certificate's symmetry grade matters more here than anywhere.
Size-wise the marquise is the value champion: a 1-carat marquise faces up around 11.5 × 5.5mm — more length than a 1.5-carat round shows in any direction. For the wedding stack, chevron and V-shaped bands echo the points beautifully, while a slim straight band worn slightly apart gives the outline room to breathe. French-tip prongs protect the points without hiding them.
Marquise diamond FAQs
What is a marquise diamond?
A marquise diamond is an elongated brilliant cut with pointed ends — 58 facets arranged in a boat-shaped outline. Carat for carat, the marquise cut shows the largest face-up area of any diamond shape.
Do marquise diamonds look bigger?
Yes — dramatically. A 1-carat marquise ring can read visually close to a 1.5-carat round because the shape spreads its weight across a longer outline.
Does a marquise have a bow-tie?
Most do — like ovals and pears, marquise diamonds show a faint dark bow-tie across the centre. Well-cut stones keep it subtle; ours are selected to do exactly that.
Are marquise diamond rings durable?
Very — provided the two points are protected. Our marquise diamond rings set each tip in a V-shaped prong, shielding the most vulnerable part of the stone from knocks.
What is a marquise wedding band?
A marquise wedding band is contoured to nest against the pointed centre stone — usually curved or notched so the two rings sit flush on the finger.
Is the marquise cut making a comeback?
Strongly — the marquise cut reads vintage and modern at once, and its size-per-carat economics make it a natural fit for lab-grown buyers.
