If one seeks "IDEAL" in a fancy shape, you will NEVER select an 80% deep Princess cut over a 65% depth one provided they have equal light return and brilliancy. The 65% depth one will be SUPERIOR simply then because it does look larger. The 80% depth stone may be a great performer, but it falls down on the apparent size issue. This means it could NOT ever be IDEAL, if something BETTER equals its light performance and also has a better attribute, namely apparent size.
You can readily select the finest POTENTIAL fancy shapes by numbers and parameters. Right now you cannot predict which ones will give the very finest light return, but you can eliminate all the stones that will be too thin, too thick, not durable, or ugly in length to width ratio. This is not an imaginary benefit that was dreamed up somewhere, but comes from years of grading diamonds and being interested in what other experts want and expect from the finest fancy shapes. An ugly fancy will NEVER be an IDEAL. A very deep fancy will never be a true IDEAL. A fragile stone will never be IDEAL. Too deep a stone, no matter how brilliant, is not IDEAL, Too thin a stone, no matter how large or accidentally brilliant, will never be IDEAL.
IDEAL is the ULTIMATE, not simply performance based on brilliancy. While strictly brilliancy may be the way the general industry would like to grade fancy shapes and/or rounds, so that any diamond, no matter how poorly cut, but brilliant, is "IDEAL, is a foolish notion. It would be a very biased way approach that would favor cutters and dealers at the expense of integrity and those few consumers who still have some degree of faith in diamond sellers.
IDEAL is an absolute concept of TOP QUALITY in cut and light return and it ought to be seen as encompassing all these aspects of each stone so judged. Anything less is not really an unqualified Ideal cut.
The AGA Cut Class grades provide the shape information that one adds to brilliancy information. This brilliancy information can be from Ideal-Scopes used with round diamond and presently from the BrillianceScope or Isee2 system for rounds and fancy shapes. This combination gives dealers or consumers the tools and information for judging if a diamond is truly IDEAL.
