Cushion Lab Grown Diamond

IGI (International Gemological Institute) certification means an independent lab has verified the stone's carat weight, color, clarity, and cut characteristics rather than relying solely on the seller's own grading. Every cushion lab grown diamond in this collection carries that certification, so the specs listed on each product page are third-party verified.

A cushion cut combines a squared outline with rounded corners, giving it a softer silhouette than a princess cut while still showing strong brilliance similar to a round cut. It's a popular choice for vintage-inspired or halo settings where a slightly softer geometric shape is preferred.

This collection currently spans from just over 1 carat up to more than 10 carats, so it covers everything from an accent-scale stone to a major statement diamond. Each listing shows the exact carat weight, so you can filter by size to match your budget and setting.

Stones range from D (colorless) to H color and from VS2 to VVS1 clarity, and both factors influence price alongside carat weight. A D or E color stone with VVS clarity will cost more than a G or H color stone of the same size, even after the same percentage discount is applied.

Yes, cushion cut is one of the most commonly chosen shapes for engagement rings because it pairs well with both vintage and modern settings. Since these are loose, unset stones, you can pair one from this collection with a setting from your jeweler of choice.
