Choosing your cushion cut diamond

Cushion cut diamonds offer a softer outline with rounded corners. Browse natural and lab grown options, then compare square and elongated proportions as well as the facet pattern of each stone. We can help you find a cushion that suits a solitaire, a halo or a custom engagement ring.

Do all cushion cut diamonds have the same appearance?

No. Cushion diamonds can differ in outline and facet arrangement. Rounded corners are a shared feature, but proportions and light patterns should be judged stone by stone.

How do I choose between a square and an elongated cushion?

Compare the length-to-width ratio and measurements to see how the outline changes. Review the individual stone's images or video, since cushion diamonds can vary in both their silhouette and pattern of sparkle.

Can I choose natural or lab grown cushion cut diamonds?

Yes. Use the Natural and Lab Grown tabs above to compare the available cushion cut diamonds in either category.

Can I choose a setting after selecting my diamond?

Yes. Select a diamond to view its details and continue through the ring builder to choose a compatible setting. Contact our jewelers for help planning a custom engagement ring.
