At 1 carat the princess cut makes a clear statement. Its square outline can look a touch smaller than a round of equal weight but carries striking brilliance. This shape suits modern buyers who want strong sparkle and clean geometry. Channel and tension settings protect the corners, and it looks sharp in white gold and platinum. Every lab grown stone shown is GIA or IGI certified, so you can compare cut, colour and clarity at a glance. Lab grown diamonds give this size and shape at a fraction of the cost of an equivalent mined stone, with identical sparkle. Stock updates continuously; if you do not see the exact combination you want, our team can source it.

How big does a 1 carat princess diamond look?

Its square outline can look a touch smaller than a round of equal weight but carries striking brilliance. Carat measures weight rather than diameter, so cut and shape strongly affect how large the stone appears.

Why choose the princess cut at 1 carat?

The princess cut is a square brilliant with sharp corners and vivid sparkle, offering the fire of a round in a contemporary geometric outline.

Are 1 carat princess lab grown diamonds certified?

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

How should a 1 carat princess diamond be set?

Channel and tension settings protect the corners, and it looks sharp in white gold and platinum.
