Q: Are all square engagement rings 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.

Q: Are princess engagement rings more expensive than round engagement rings?

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.

Q: How are princess-shaped engagement rings and cushion-cut engagement rings different?

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

Q: Do princess engagement rings or round engagement rings look bigger?

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.
