💎 Price shown after selecting your center stone.
Use our Ring Builder to choose your preferred diamond — carat, cut, and quality. Your final price is calculated once your center stone is selected.

Of the six cuts we set this way, the emerald is the one the angle changes most. Set square, an emerald cut is a formal rectangle and reads as a signet. Rotate it thirty degrees on the band and the parallel lines of its steps run diagonally against the parallel edges of the band, and the whole ring turns into a piece of geometry rather than a formal setting.

The setting

The tabs take opposite corners - the cropped corners of an emerald cut are flat facets, which gives a tab a proper surface to fold onto rather than a point to pinch. That is why this cut takes a two-tab setting more securely than most. The band is flat-topped and wide, with the top face polished to a mirror, and because an emerald cut is mostly one large open table you get the unusual effect of seeing the band reflected in the stone and the stone reflected in the band.

About our lab-grown diamonds

Every stone we set is a lab-grown diamond — the same carbon crystal structure, hardness and optical behavior as a mined diamond, grown rather than extracted. Center stones of 1 carat and above ship with an IGI certificate stating carat, cut, color and clarity. Melee and pave stones are matched to the same color and clarity range but are not individually certified.

About the photographs

The photographs on this page show this setting made with one specific stone. The setting is exactly what you will receive; a different center stone changes the proportions — a heavier one spans more of the finger and sits a little higher. We photograph every finished ring and send you those images before it ships.

Common questions

An emerald cut shows inclusions more than other shapes. What should I choose?
Go a grade higher in clarity than you would on a brilliant cut. The long open facets of a step cut act like windows, so VS1 or better is where we would start on any emerald above one carat. Cut quality matters as much as clarity here, and we check both before setting.

Does the angle make the ring sit crooked on the finger?
No - the band itself is straight, and it is the stone that is rotated on top of it. The ring seats normally; only the diamond is on the diagonal.

Do the photographs show the exact ring I will receive?
The setting, yes — those are photographs of this setting made in our workshop. The diamond in them is one specific stone, so a different center stone will not look identical: a heavier one covers more of the finger and sits slightly higher. We photograph every finished ring and send you those images before it ships.

Is the center stone certified?
Yes. Every center stone of 1 carat and above ships with an IGI certificate stating carat, cut, color and clarity. Accent and pave stones are matched to the same color and clarity range but are not individually certified.
