Named for its pillow-soft outline, the cushion cut pairs rounded corners with large, light-catching facets for a warm, romantic sparkle that reads as inherited rather than bought. It's the cut for the woman drawn to vintage character without giving up modern brilliance. Our cushion lab-grown diamonds carry the same fire and hardness as a mined stone, set in solid recycled gold across solitaire, three-stone and bezel styles, made to order. Soft corners, warm presence, a silhouette that never goes out of style.

Is the cushion cut vintage-looking?

It has its own softer, broader flash rather than the round's pinpoint fire.

Does it sparkle as much as a round?

It has its own softer, broader flash rather than the round's pinpoint fire.

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.
