Princess Cut Engagement Rings

The Princess Cut

Princess Cut Engagement Rings

A princess cut diamond is a square brilliant with sharp, uncut corners. It has the most light of the square shapes, it keeps more of the rough than a round and so costs less per carat, and its clean geometry suits modern settings in a way softer shapes do not. Every princess cut engagement ring here is made to order in our Los Angeles atelier, with the corners held by prongs or a bezel, because the corners are where a princess is vulnerable and where a setting earns its keep.

A princess faces up slightly smaller than a round of the same weight, because more of its weight sits below the table in the pointed pavilion. In exchange it sparkles almost as much as a round and gives you more carat for the same spend. Most princess cuts sit between 1.00 and 1.05 in ratio, a true square; a touch rectangular is a personal choice and reads a little longer on the finger.

Two ways to own one

Build your ring. Choose a setting below, then pair it with a natural or lab diamond from our inventory. A ROSI™ Score Report, our gemological intelligence, reads the cut performance and fair market position of any natural diamond you are considering, and John Anderson, our Lead Gemologist, reviews the shortlist with you.

Choose a Select ring. The Select rings arrive complete, with an IGI certified lab diamond already matched to the setting in the carat weight you choose.

How to choose a princess cut diamond

• Corners. Look for four corners that are sharp and even. Chipped or rounded corners are a cutting flaw. The prongs cover them in the finished ring.
• Ratio. 1.00 to 1.05 is a square princess. Above 1.08 reads rectangular. Both are fine; the setting is modeled to the diamond.
• Color. Princess cuts show color in the corners. H or better in white metal; yellow and rose gold forgive down to J.
• Clarity. The brilliant faceting hides inclusions well in the center; the corners show them. VS2 is usually clean; SI1 needs a look.
• Setting. Four prongs on the corners, or a bezel, for every princess. A channel set band suits the geometry. A halo on a princess reads as a cushion from across the room.
