The round brilliant cut is the benchmark every other cut is measured against. Its facet pattern is optimised to return the most light, which is why it reads as the brightest, most classic diamond on the hand. A round lab-grown diamond gives you that textbook brilliance with a cleaner origin and more carat for your budget — identical hardness and grading to a mined stone. It suits every setting: a slim solitaire for understated classicism, a hidden halo for extra sparkle, a cathedral to lift it into the light. Set in solid recycled gold and made to order.

Why is the round cut the most popular?

Per carat it can present a slightly smaller face than elongated cuts; a halo or slim band adds presence.

Does a round look smaller than other cuts?

Per carat it can present a slightly smaller face than elongated cuts; a halo or slim band adds presence.

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.
