Although cushion cut diamonds have experienced a swell in popularity among celebrities and common buyers alike, deBebians cushion cut halo engagement rings are a part of an old tradition. At the turn of the 20th century, jewelers designed the cushion cut so that rings would look its best by candlelight without revealing its flaws. Once the age of electricity arrived, the diamond cut fell out of favor. Under the glare of bright light, the stones women wore were not as impressive. The technology did not exist to get a clean cut. The revival of the cushion cut has probably been led by many celebrities who have chosen this style for their weddings. The flat face on the bottom of a cushion-cut gemstone is open and the stone itself is a rectangular or square shape. The corners are round and the facets are cut to give the stone its most brilliant luster. It has to compete with some other modern cuts that seem more brilliant, but many people who love this cut choose it because it is classic and romantic. Its qualities make it a timeless cut, in many ways. One of the distinctions that can be made between the antique cushion-cut gems and modern cushion cuts is in the faceting. The modern cuts may have three-dimensional concave facets or the popular Portuguese-cut facets that look like checkerboards. Some of the most famous diamonds the world knows of are cushion-cut. These include the blue Hope Diamond, yellow Tiffany Diamond, the Regent Diamond and the Smithsonian’s 423 ct. Logan Sapphire.
