The Anatomy of a Brilliant and Step Cut Diamond (5.02)
The above illustrates a “modern round brilliant cut” but the same term can apply to all other brilliant cuts, (pear shape brilliant, oval shape brilliant, etc.). Step-cuts, such as the emerald cut, will not have upper and lower halves or half facets and star facets -- which distinguishes them from brilliant cuts.
The terminology of the different characteristics of the brilliant cuts is very important when communicating with other dealers, clients or your diamond cutter.
