Square cut diamonds most commonly refer to a princess cut diamond, which has pointed corners and sleek style lines. But princess shaped diamonds aren't the only square shaped diamonds. Asscher cut diamonds, radiant cut diamonds, and cushion cut diamonds all offer a square look, as well. Shop all of these square shaped, paying attention to the different cut designs to select the ideal square shaped diamond for your custom jewellery.

FAQs About Square Cut Diamonds

Both an Asscher cut diamond and a Princess cut diamond are square in shape, but the cuts of the shapes are very different. Asscher cut diamonds feature a large pavilion with rectangular facets that create tapered corners. Princess cut diamonds feature straighter lines and pointed corners.

A princess cut diamond has sharper corners and straighter style lines than a cushion cut diamond, which features softer corners and a more convex shape overall. Both are available in square and rectangular options.

All square shaped diamonds are fancy-shaped diamonds, which can be up to 25% less expensive than a round diamond of the same carat weight and quality.

A one-carat, princess cut diamond is roughly 5.5mm, while a one-carat, cushion cut diamond is roughly 6.5mm x 5.5mm. Check out Blue Nile's size chart to compare all square diamond shapes.
