FAQs about Princess Cut Engagement Rings

Although a square-cut engagement ring typically refers to a princess-cut ring, Asscher-, radiant-, and cushion-cut diamonds can all be featured in a square engagement ring.

No—in general, it's actually the opposite. Fancy-cut diamonds, such as the princess-cut diamond, are up to 25% lower in price than a round brilliant diamond of the same carat weight and quality.

Princess-cut engagement rings feature pointed, 90-degree corners, while cushion-cut engagement rings showcase diamonds with softer corners.

When you have two stones of equal carat weight, typically, a round diamond will appear larger than a princess cut. The Blue Nile size chart shows how each diamond shape measures up at equal carat weights.

Beautiful Princess Engagement Ring – and a great experience

Videos, GIA report and other resources made choosing a diamond as easy as possible. The diamond looks exactly as expected and the ring is beautiful. The setting is nice and simple, and looks exactly like the photos/online preview with the diamond I chose. The ring arrived very quickly! I ordered on a Saturday and had it by Tuesday morning

Princess Cut Engagement Ring Review

Engagement Ring

This ring is absolutely gorgeous. I was a little worried at first the setting would be too much and take away from the center diamond. It was just the opposite. It made the 2 ct Princess cut diamond look amazing. The online chat was helpful in narrowing down my choices. I was a little concerned at first with purchasing online, but after reading the reviews and talking to several friends, I felt better. I liked the all the options and choices available as well as being able to buy a wedding band to match. The ring arrived as promised on time. I couldn?t be more pleased. Her reaction was priceless. We are both widows (young) and this was the right way to start a new beginning. Thank you Blue Nile!
