FAQs about Square Engagement Rings

Square-cut diamond engagement rings showcase a center stone with a square silhouette. This can include princess, Asscher, radiant, or cushion-cut diamond rings.

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

A princess-cut diamond features 90-degree corners and straighter style lines. A cushion-cut diamond features softer corners and a more convex shape.

Princess-cut diamonds come to a point in the four corners. Asscher-cut diamonds feature angled corners that display a slightly softer appearance.

Beautiful Square Engagement Ring – and Great service

When my fiancée asked me to help pick the ring during a pandemic I thought this would be a very difficult process. Instead it was very easy and I was able to get the ring I dreamed of. We did use the gem assistant to help with picking the right stone and his assurances made us feel so at ease about purchasing a ring sight unseen. It is truly the most beautiful ring. I'm looking forward to ordering the matching band as well now we know how easy and perfect it will be.
