Ideal Cut Diamond
Everyone has their own opinion
on what Ideal cut Diamond is. Some people prefer a diamond
to have a somewhat larger table, say around 60%, so the
diamond looks bigger; some want the
Tolkowsky Ideal cut,
as calculated in the early 20th century by mathematician
Markov Tolkowsky. The diagram below describes the Class 1
and 2 grades of GIA. They are the largest body in the world
for diamond grading, and we use their classifications to
grade our diamonds. Class 1 is Ideal. Class 2 is Very Fine,
Class 3 is fair, and Class 4 is Poor. The GIA's definition
of "Ideal - Very Fine" Class, and are as follows:
Please keep in mind that diamonds
other than round brilliant do not always have their cuts
measured in such detail because they are classified as
"fancy cut" diamonds and have very loose tolerances. When
buying a diamond, especially a round brilliant cut diamond,
it is always best to have a complete analysis of cut. This
will tell you all the specifications of the diamond's cut
such as table percentage, depth percentage, etc., usually
obtained from a scope (or mega-scope). Ask your jeweler for
this report on cut if you are making a large diamond
purchase. |
