Princess Cut Engagement Rings
The princess cut is the square that sparkles like a round — invented in the 1980s to pack brilliant-cut fire into a modern, sharp-cornered outline, and it wastes so little rough that a princess cut ring consistently delivers the most sparkle per dollar of any shape. Our princess cut engagement rings run from $903 to $4,311 across 206 designs.
Princess cut ring styles
A ring with princess cut diamond brilliance works everywhere: crisp solitaires, geometric halos, and channel-set bands where the square outline sits flush. Princess cut wedding rings pair naturally — the straight sides nest against a band with no gap.
The lab-grown edge
Princess cut diamond engagement rings put the four corners at risk unless properly set; every one of ours uses corner-protecting prongs, and lab-grown IGI-certified stones make upgrading carat or clarity painless.

What to know before buying a princess cut
The princess hides weight underneath: its deep pavilion means a 1-carat princess faces up around 5.5mm square — noticeably smaller than a 1-carat round's 6.4mm spread. Budget accordingly: to match a round's visual presence, step up roughly a quarter carat. The consolation is price — that same efficiency in cutting makes the princess cheaper per carat than almost anything else.
Keep the ratio between 1.00 and 1.05; beyond that the square reads accidentally rectangular. Corners are the shape's whole risk profile: they must sit inside prongs, and any chip or inclusion at a corner is a fault line waiting for a knock — check the certificate's clarity plot for corner inclusions specifically. Set in a channel band, the princess earns its keep: straight sides align edge-to-edge into an unbroken ribbon of light no round can produce.
Princess cut FAQs
What exactly is a princess cut?
A princess cut is a square brilliant — the fire of a round rearranged into four sharp corners. It is the youngest classic shape, dating only to the 1980s.
Is a princess ring cheaper than a round?
Meaningfully — a princess ring keeps up to 80% of the rough crystal versus roughly 50% for a round, and that efficiency flows straight into the price per carat.
Are princess cut rings durable?
Yes, with one condition: the four corners must sit inside protective prongs. Every one of our princess cut rings is set that way — corners are the shape's only weak point.
What are princess cut diamond rings usually set in?
Four corner prongs for solitaires, or channel settings where princess cut diamond rings excel — the straight sides line up edge-to-edge with no gaps, something round stones cannot do.
Do princess cut diamond earrings exist?
Yes — princess cut diamond earrings put the same square brilliant on the ear, usually as studs. Browse our stud earrings collection for square-set pairs.
Princess or cushion for a square look?
Princess for crisp, modern geometry; cushion for softness and vintage character. Both deliver serious sparkle — the corners are the real decision.
