This is a Diamond Quality Document (DQD) issued by the American Gem Society Laboratory (AGSL). Click on the thumbnail image to view the full size document. Notice that it provides all of the measurements and proportions of the diamond in addition to the standard clarity, color, and carat weight information found on most diamond grading reports. A label indicating the results of our own Computerized Proportions Analysis verifying that the diamond has Ideal Cut Proportions appears beneath the "comments" section of the diamond grading report in the lower left hand corner... This particular diamond happens to have "Super Ideal" Proportions which is a tighter range of proportions within the broad range of criteria created by the AGS Laboratory for the Ideal Cut classification. The term "Super Ideal" by our definition is used to describe a round brilliant ideal cut diamond within the following range of characteristics:
-
Total depth between 59 - 61.8%
-
Table diameter between 53 - 57%
-
Crown angle between 34.3 - 34.8 degrees
-
Pavilion angle between 40.6 - 40.9 degrees
-
Girdle: 1.0% thin to 1.8% medium
-
Culet: GIA none or AGS pointed
-
Polish: GIA Excellent or AGS Ideal
-
Symmetry: GIA Excellent or AGS Ideal
Now this is not to say that you can
not find non-ideal and standard ideal cut diamonds that exhibit levels
of brilliance, dispersion and scintillation equal to the visual
performance of a Super Ideal Cut Diamond... Not at all...
Merely that it is easier to find and ideal cut diamond that exhibits a
high degree of visual performance within the aforementioned center range
of the ideal cut classification.
Note that the Pavilion Angle is the most critical of all the angles of a
diamond as it is the reflective surface that reflects light back out the
top of the diamond... We consider the Crown Angle to be the second
most critical angle on a diamond... Similar visual results to
Super Ideal Cut Diamonds can often be found in diamonds with opposing
degrees of depth for these two angles, in other words a diamond with a
deeper Pavilion Angle such as 41.2 degrees with a shallow Crown Angle of
33.9 degrees... Or a shallow Pavilion Angle such as 40.4 degrees
with a steeper Crown Angle such as 35.3 degrees. Don't worry if
all of this makes your head spin, we hand select all of the diamonds
contained within The Private Reserve of Nice
Ice for maximum visual performance... We've crunched all the
numbers, eliminated the diamonds that don't perform well or which
contain inclusions which are undesirable or detrimental to the
durability of the stone... All you have to do is look at the list
and decide which one is right for you.
