Swiss cut diamonds are the late 19th-century predecessor to the 20th century Single Cut. Their crowns are built up out of a table facet, eight crown star facets, and eight bezel facets. Main facets are lacking which forms the difference with Brilliant Cut stones. Their pavilions are built up out of eight main and eight bezel facets.
These stones have been mainly used as small side-stones to compliment larger Brilliant Cuts. They are typically found in late 19th and early 20th-century jewelry until they were replaced by the New Single Cuts around the beginning of the Art Deco period. Single Cuts were easier and cheaper to manufacture and took over the role of the standard cut for melée-sized stones.
