One carat is the enduring benchmark for an engagement ring — substantial enough to make a statement, balanced enough to wear every day without a second thought. Because our diamonds are lab-grown, a full carat sits comfortably within reach, with the same cut, colour and clarity grading you'd expect from a mined stone.

Explore one-carat rings across every cut and setting: a round solitaire for maximum brilliance, an oval for an elongating look that wears larger than its carat, a bezel for clean modern lines, or a three-stone for added meaning. Each is set in solid recycled gold, never plated, and made to order.

How big does a one-carat diamond look?

It's the most-chosen size for exactly that reason — present without getting in the way of daily life.

Is one carat a good everyday size?

It's the most-chosen size for exactly that reason — present without getting in the way of daily life.

Are lab-grown diamonds real diamonds?

Yes. A lab-grown diamond is chemically, physically and optically identical to a mined one — same hardness, same fire, same sparkle. The only difference is origin: ours are grown rather than dug, which means a cleaner provenance and far more carat for your budget.

How long does my ring take to make?

Each ring is made to order. Please allow 2–3 weeks before it ships — your stone, set by hand, in the metal and setting you choose.
