Dive into the world of cushion cut engagement rings at Diamond Domain, where timeless romance meets modern sustainability. Our lab grown diamonds offer the perfect blend of classic allure and earth-friendly luxury, combining ethical beauty with lab grown brilliance.
-
Cushion cut engagement rings are celebrated for their unique pillow-shaped design, which merges the geometric precision of a rectangle with the soft curves of a round cut. This distinctive shape maximizes brilliance with its rounded corners and larger facets, creating a romantic and elegant look that is ideal for engagement rings. With the ability to reflect light beautifully and conceal inclusions, cushion cut diamonds are the perfect symbol of everlasting love.
-
At Diamond Domain, we are committed to offering luxury that is both earth-friendly and accessible. By choosing lab grown diamonds, we significantly reduce the environmental impact associated with traditional diamond mining. Our lab grown cushion cut diamonds deliver the same brilliant beauty and durability as mined diamonds but at a more affordable price, allowing you to enjoy ethical luxury without compromise.
-
Discover the timeless elegance of our lab grown cushion cut engagement rings, where lab grown brilliance meets refined design. Choose from our classic cushion cut rings, showcasing the pristine beauty of the diamond in simple yet sophisticated settings. For a bold statement, explore our halo cushion cut rings, which amplify the brilliance of the center stone with a ring of smaller diamonds. If you’re looking for something unique, our diverse collection includes everything from sleek, modern minimalist designs to richly detailed antique settings, each tailored to reflect your personal style and celebrate your love.
-
At Diamond Domain, we understand that every love story is unique. That’s why we offer bespoke services to help you create a custom cushion cut ring that reflects your personal journey.

Ready to Create Your Sustainable Cushion Cut Engagement Ring?

A cushion cut diamond is square or slightly rectangular with rounded corners and large facets, like a pillow. It has a softer, warmer sparkle than a round brilliant and a romantic, vintage character that has been popular for more than a century.
Cushion engagement rings suit buyers who like antique-inspired designs, who want a square shape without sharp corners, and who prefer a glow of light over pinpoint flashes. Cushions come in two facet styles: a chunky cushion with broad, distinct flashes, and a crushed-ice cushion with a finely broken-up sparkle. Both look beautiful in a halo, which is the classic cushion setting, as well as in a solitaire or three stone ring.
Diamond Domain sets cushions with IGI-certified lab grown diamonds in F–G color and VS1–VS2 clarity, selected for even proportions and bright light return. Settings are available in 10K, 14K and 18K gold, platinum, and custom 22K or 24K gold.
Lab grown diamonds are real diamonds with the same hardness and fire as mined stones, priced well below them at the same grade. Cushions are also priced below rounds per carat, so the shape stretches a budget further.
Every cushion ring includes free engraving, a lifetime warranty, free insured worldwide shipping, free US return shipping and 30-day returns.
Frequently asked questions
What is the difference between a cushion cut and a round diamond?
A cushion is square or rectangular with rounded corners, while a round is circular. Cushions have larger facets that produce broader, softer flashes of light; rounds have smaller facets that produce sharper, brighter sparkle. Cushions are usually priced below rounds at the same carat weight.
Should I choose a square or elongated cushion?
A square cushion looks classic and compact and suits a halo well. An elongated cushion looks larger across the finger and lengthens the hand, similar to an oval. Both are cut from the same shape family, so the choice is about the look you prefer.
How much does a cushion cut lab grown diamond engagement ring cost?
Cushion cut lab grown diamond engagement rings at Diamond Domain start at $1,049. Cushions retain more of the rough crystal than rounds, so they are priced below rounds at the same carat weight. A lab grown cushion is priced far below a mined cushion of the same IGI grade.
Are cushion cut lab grown diamonds durable and certified?
Yes. The rounded corners of a cushion remove the chip-prone points of a princess cut, and diamond scores 10 on the Mohs hardness scale regardless of origin. Every cushion center stone is certified by IGI, laser-inscribed with its report number, in our standard F–G color and VS1–VS2 clarity, and covered by our lifetime warranty.
Can I return a cushion engagement ring if the size is wrong?
Yes. You have 30 days from delivery to return or exchange the ring, and return shipping inside the US is free. If you are unsure of your size before ordering, contact us and we will help you confirm it.
