Marquise natural diamonds: what to look for
A ratio of 1.75 to 2.25 gives the classic marquise; both points should line up, and each is protected by a V-shaped claw. Our marquise diamond guide covers the shape in more detail.
Marquise diamond sizes and prices
Carat measures weight, not size. These are the typical measurements and lowest prices of the marquise natural diamonds in our stock today, by carat size:
| Carat | Typical size | Available | From |
|---|---|---|---|
| 1 carat | 10.0 x 5.2 mm | 3,556 | $1,801 |
| 1.5 carat | 11.3 x 5.9 mm | 1,035 | $3,621 |
| 2 carat | 12.7 x 6.5 mm | 706 | $8,180 |
| 3 carat | 14.7 x 7.4 mm | 264 | $16,689 |
| 5 carat | 17.5 x 8.9 mm | 31 | $73,481 |
Marquise natural diamond prices
Today our marquise natural diamonds range from $448 to $2,184,232, across 12,398 stones. Carat weight makes the biggest difference, followed by colour, clarity and cut. Prices step up at the whole and half carat marks, so a stone just over 1.00, 1.50 or 2.00 carats gives the size for the smallest premium.
Natural or lab grown?
A natural diamond is formed over billions of years and each one is rare; many buyers value that origin. A lab grown diamond of the same grades costs far less. From one carat up, our lowest priced marquise diamond today is $1,801 natural, against $455 lab grown. Compare marquise lab grown diamonds.
Choosing colour and clarity
Up to about 1.5 carats, G or H colour and VS2 or SI1 clarity usually look white and clean to the eye. From 2 carats colour and inclusions are easier to see, so G or better and VS2 or better are worth considering.
Setting your diamond
Every diamond here can be set in an engagement ring, pendant or earrings made to order in our Bourton-on-the-Water workshop, hallmarked in the UK. Browse engagement rings or design your own. If the stone you want is not listed, our team can source it for you.
