At 1 carat the marquise cut makes a clear statement. A marquise looks larger than almost any other shape at equal weight and slims the finger. This shape suits those who want maximum finger coverage and a dramatic, regal shape. V-tip settings protect the points, and symmetry between the two halves is worth checking closely. Every natural, mined stone shown is GIA or IGI certified, so you can compare cut, colour and clarity at a glance. A natural stone of this size is a genuine rarity, and the certificate confirms its weight, colour and clarity. Stock updates continuously; if you do not see the exact combination you want, our team can source it.

How big does a 1 carat marquise diamond look?

A marquise looks larger than almost any other shape at equal weight and slims the finger. Carat measures weight rather than diameter, so cut and shape strongly affect how large the stone appears.

Why choose the marquise cut at 1 carat?

The marquise is an elongated, boat-shaped brilliant with pointed ends, giving it one of the largest visual footprints of any cut for its carat weight.

Are 1 carat marquise natural, mined diamonds certified?

Yes, every 1 carat marquise diamond is graded by GIA or IGI, with a report confirming carat weight, colour, clarity and cut.

How should a 1 carat marquise diamond be set?

V-tip settings protect the points, and symmetry between the two halves is worth checking closely.
