The first round brilliant...
Old European Cut
It wasn't until 1874 after Henry Morse patented the steam-powered bruter, that a 'round' shape was achieved. This development enabled the establishment of the round brilliant as the dominant cut.
Old European Cuts/American Cuts are by definition round (though sometimes ‘roundish’). Compared to a modern brilliant, they have a much smaller table, taller crown, shorter star facets, an open culet and shorter lower-half facets which create the blockier (lovely!) flower pattern in the pavilion.
