Summary of the forms of diamond cuts
The term brilliant is today so closely associated With the mineral diamond that people often speak of "brilliant" when they mean the mineral diamond.
The brilliant is the "classic" among all cut forms. Its designation applies exclusively to the circular form of cut which exhibits at least 32 facets and a table on the crown, and at least 24 facets and a culet on the pavilion.
The description diamond assumes the genuineness of the stone.
The facets are described as follows (Fig 191):
| on the crown | 8 table facets |
| 8 upper main facets | |
| 16 upper girdle facets | |
| on the pavilion | 8 lower main facets |
| 16 lower girdle facets |
Simplified varieties of the brilliant cut are
-
the eight-cut, also called Single-cut, with 8 facets each on the crown and pavilion (Fig 192);
-
the sixteen-cut, also called Swiss-cut, with 16 facets on both the crown and the pavilion (Fig 192).
Among the modified brilliant cuts are (Fig 192):
-
the Navette or Marquise
-
the Pear or Pendelaque
-
the Oval and
-
the Heart cut.
