The cushion cut is an antique and romance-inspiring diamond cut that's been around for more than a hundred years. Until the early 20th century, the cushion cut was the go-to diamond style. It fell out of favor, but has regained popularity recently thanks to its classic look.

Cushion Cut Diamond Features

Also referred to as "pillow cut," a cushion cut diamond is square or rectangular and has rounded corners and large facets. The large facets make the stone less brilliant than some more contemporary cuts, and highlight the diamond’s clarity -- so the clarity and color of cushion-cut stones are particularly important. Standards for this cut vary more than for other diamond styles. Cushion cut stones require a four-pronged setting, at minimum.
