It’s hip to be square and—when it comes to diamond shapes—circular.

The Knot’s most recent Market Intelligence Report reveals that round and princess cuts topped the list of diamond shapes, with 53 percent of brides choosing a round-cut center stone and 30 percent opting for a princess-cut diamond.

Every other available cut came in at 3 percent or less, with heart- and trillion-cut center stones proving the least popular.
