A cushion-cut diamond combines the modern round brilliant cut with the more classic square-cut diamond, creating a square shape with rounded corners. A princess diamond would be a close consideration for someone who wanted a square diamond; however, the cushion cut has a distinctly more vintage feel. Without a single hard edge or corner, its 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. The cushion cut produces slightly less wasted raw material during production, and so costs slightly less than a round brilliant cut.
