A lab-grown diamond engagement ring gives you a stone that is chemically and optically identical to mined — graded on the same cut, colour, clarity and carat scale — but grown rather than extracted. For the modern bride, that means a larger, brighter centre stone with a provenance she can feel good about. Every Alya Stone ring is built in solid recycled gold, never plated, so it holds up to daily wear and ages into an heirloom.

Choose your silhouette: a classic solitaire for clean, enduring simplicity; a three-stone to mark past, present and future; a toi et moi for two stones in conversation; or a hidden halo for quiet extra sparkle. Explore by cut — round, oval, cushion, emerald, pear, marquise, Asscher and radiant — and by carat, from a one-carat everyday icon to a three-carat statement. Each ring is made to order, your stone set by hand.

What's the difference between a solitaire and a three-stone ring?

Elongated cuts — oval, marquise, pear and emerald — spread their weight across the finger and tend to look larger than a round of the same carat.

Which cut looks largest for the carat?

Elongated cuts — oval, marquise, pear and emerald — spread their weight across the finger and tend to look larger than a round of the same carat.

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.
