Marquise cut diamond

Marquise · 1.00 ct minimum · white · $510 per carat

Roughly 9.9 × 5.1 mm face up — the measurement a setter works from.

360° footage of a stone of this cut. Yours is allocated at dispatch and will meet or beat the specification below.

Marquise cut

The largest face-up size per carat of any shape.

Two points and a long body make the marquise the most efficient shape for apparent size. It is unforgiving of poor symmetry, and like the oval it can carry a bow-tie through the center.

Size

1.00 ct minimum

The size you choose is the floor. Stones ship at that weight or up to 10% over — 1.00 to 1.10 ct — and never under.

Body color

$510 / ct

Colorless to near-colorless, graded D to F. White diamonds are $510 a carat; fancy colors are $600.

What we guarantee

Size
At least 1.00 ct. Up to 1.10 ct. Never less.
Clarity
VS1 or better. Often better.
Color
D to F. Often D.
Cut
The cut you chose, graded Excellent or above.
Report
IGI or GIA, shipped with the stone.

We move enough volume that we will not pretend to know which stone in the parcel becomes yours. What we will do is put a floor under every part of it and let the variance run in your favor — the weight, the clarity and the color can come in above what you paid for, and regularly do.

For example

You order 1.00 ct · VS1 · F.
You might receive 1.10 ct · VVS1 · D.

Same price either way.

What VS1 and D–F actually mean
VS1
Very slightly included. Minor inclusions, hard to locate even under a loupe.
Color D
Absolutely colorless. The top of the scale, and mostly bought for that fact.
Color E
Colorless. Distinguishable from D only by a grader with comparison stones.
Color F
Colorless. The last grade before faint warmth appears under laboratory light.

Buying a marquise

Two points and a long body make the marquise the most efficient shape for apparent size. It is unforgiving of poor symmetry, and like the oval it can carry a bow-tie through the center.

Proportion to expect: 1.85–2.10 is where it looks intentional rather than accidental. We cut to the middle of that range, so a marquise from us looks like the shape you pictured rather than a stretched version of it.

Every marquise is laboratory grown, graded by IGI or GIA, and shipped with its report. If the stone that arrives is not the one you want, request a return authorization within 30 days.
