Cushion diamonds — common questions

Are cushion diamonds a good choice for an engagement ring?: Yes. Cushion diamonds are a versatile, enduring choice, and every stone we carry is independently certified (GIA or IGI). You can set any of them into a matching ring through our build-your-own flow.
Do you offer both natural and lab-grown cushion diamonds?: We carry both. Use the Natural and Lab filters to compare — lab-grown gives you more size for the budget, while natural carries traditional rarity. Both come fully certified.
How do I set a cushion diamond into a ring?: Choose your stone, then pick a compatible mounting in build-your-own. We only pair a stone with a setting sized within about 0.1 ct of it, so the fit is correct and the piece is hand-finished in our studio.
