The pear-cut diamond shape is a unique combination of the round and marquise shapes. As one of only two asymmetrical diamond shapes, Pear-cut diamonds are as rare as they are stunning. Considered a modified brilliant-cut, the pear-cut sparkles as exquisitely as round and princess diamond. Only four percent of diamonds are cut into the pear shape, and only a small percentage of those are cut correctly. For these reasons, finding a well-cut pear-shaped diamond is truly an extraordinary find.
