Collection: Cushion Cut Lab Grown Diamond Rings

A cushion cut diamond has a square or rectangular shape with softly rounded corners resembling a pillow or cushion, hence the name. When lab-grown, the diamond is created using HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) technology, producing a stone that is chemically, physically, and optically identical to a mined diamond. Luxurian Jewels offers cushion cut lab-grown diamonds set in beautifully crafted gold and platinum rings.

Yes cushion cut is one of the most popular engagement ring choices. Its soft, rounded corners give it a romantic and vintage appeal, while its larger facets produce a beautiful, distinctive sparkle with a "crushed ice" or "chunky" brilliance pattern. The cushion cut has been a favourite for over 200 years and suits both classic and modern settings. It looks stunning in solitaire, halo, and pavé band designs.

A round brilliant cut is the most popular diamond shape, optimised for maximum light return and fire. A cushion cut has a squarish shape with rounded corners and larger facets that create a softer, warmer glow with more colour dispersion. Cushion cuts retain more colour than round brilliants, which can be a benefit (warmer tones look richer) or something to factor in when choosing your colour grade. Cushion cuts also tend to cost less per carat than round brilliants.

Lab-grown cushion cut diamonds cost significantly less than mined diamonds typically 60–80% less for the same carat weight and quality. At Luxurian Jewels, pricing depends on carat size, colour and clarity grade, metal type (gold or platinum), and ring setting. Choosing a lab-grown stone means you get a larger, higher-quality diamond for the same budget compared to a natural stone. Visit the collection page for current pricing.

For a square cushion cut, look for a length-to-width ratio between 1.00 and 1.05 this gives the most symmetrical, pillow-like appearance. For a rectangular cushion cut, a ratio of 1.10 to 1.20 is ideal. The choice is purely personal preference. A square cushion looks classic and bold, while a slightly rectangular cushion appears more elongated on the finger. Luxurian Jewels can guide you on the best ratio for your chosen setting.

Yes. Lab-grown diamonds at Luxurian Jewels come with grading certificates from internationally recognised laboratories such as IGI (International Gemological Institute) or GIA. The certificate details the diamond's cut, colour, clarity, and carat weight the 4Cs along with confirmation that it is a lab-grown stone. This certificate is your assurance of quality and is important for insurance purposes as well.

Luxurian Jewels offers cushion cut rings in 14K and 18K yellow gold, white gold, rose gold, and platinum. White gold and platinum complement the diamond's brilliance and give a sleek, modern look. Yellow gold enhances the warm tones of cushion cut diamonds beautifully, especially in lower colour grades (J–K). Rose gold is a popular romantic choice that pairs wonderfully with the soft shape of the cushion cut.
