About Oval Lab Grown Diamonds
An oval has the sparkle of a round brilliant in a longer outline, and it tends to look larger face-up than a round diamond of the same carat weight. This search shows loose oval lab-grown diamonds only, each with an IGI or GIA grading report. Quality filters open on G color or better, VS2 clarity or better and an Excellent cut; widen any of them to see more. Use the length-to-width ratio under More filters to choose how slim or round your oval looks, and open any diamond to see its photos and, where there is one, its 360° view. Each diamond is sourced for your order and arrives in about 2 to 3 weeks.

Oval Diamond Questions
What length-to-width ratio is best for an oval diamond?
Most people prefer 1.35 to 1.50. A lower ratio looks rounder and a higher one longer and slimmer; set the range under More filters.
What is a bow tie in an oval diamond?
A darker band across the center of some ovals, caused by how light passes through the stone. A well-cut oval keeps it faint, so check the diamond’s photos or 360° view before you choose.
Can I set a loose oval diamond in an engagement ring?
Yes. Book a video or phone appointment and we will help you pair it with one of our settings. Loose diamonds are final sale, so we are glad to help you choose first.
