- Rose Cut - A flat based cut for a preious stone, leaving the surface covered with triangular facets, usually 24 in total.
It was introduced in the 15th century and popular during the 16th and 17th centuries.
The rose cut was the most popular form of diamond cut until the discovery of the brilliant cut at the end of the 17th century, after which its use declined.
