What is a cushion diamond?
1 Answer

A cushion-cut diamond is a diamond with soft rounded edges — it draws on an old diamond shape and it combines a square cut with rounded corners. Cushion-cut diamonds, with their larger facets, are just as dazzling as their round-cut counterparts. Find a range of antique and vintage cushion-cut diamond jewelry on 1stDibs.
