A cushion-cut diamond combines the modern round brilliant cut with the more classic square-cut diamond creating a square shape with rounded corners. It’s shape resembles a pillow; hence the name “cushion cut”. There are four main types of cushion cuts: Old Mine, which is the oldest; the brilliant cut, which offers the most brilliance; cushion modified “crushed ice’, which is one of the newest cuts; and cushion modified “hybrid”, which combines the facet style of the brilliant with the “crushed ice” facet patterns.
