Cushion Cut Lab-Grown Diamonds
The cushion cut diamond, with its soft, romantic charm and vintage appeal, is a beloved choice for those seeking a blend of classic beauty and modern brilliance. Originating in the 19th century, this cut features a square or rectangular shape with gently rounded corners, resembling a pillow—hence its name. Its large, open facets, typically 58 to 64 in number, create a captivating sparkle that balances fiery brilliance with warm, scintillating depth, making it a versatile choice for various jewelry styles.
​
Known for its ability to showcase a diamond’s color and clarity, the cushion cut’s unique faceting pattern produces a distinctive "crushed ice" or "sparkling water" effect, where light dances across the stone in a soft, radiant glow. This cut’s rounded edges lend it a softer, more romantic aesthetic compared to sharper cuts like the Asscher, making it a popular choice for engagement rings and heirloom pieces that evoke timeless elegance. Available in both square and slightly elongated rectangular variations, the cushion cut offers flexibility to suit diverse tastes and settings.
​
At Icestore, our lab-grown cushion cut diamonds embody this enduring allure while prioritizing sustainable craftsmanship. Each stone is expertly crafted to maximize its brilliance and beauty, offering an eco-conscious alternative that doesn’t compromise on quality or sparkle. Dive into our curated collection of cushion cut diamonds to find a gem that captures your unique style and tells your story with every facet.
