I am looking at the princess cut guidelines at the gemappraisers page http://www.gemappraisers.com/chrt4.htm
Can someone help me with a few questions?
1. What cut should I seek (ClassA or B etc.)I'm looking to get the best value for my dollar (7k range).
2. The table and depth ranges vary so what anything between those ranges are acceptable? Do they vary much between say table 77-82%? And the same for Depth?
Just having a hard time following how to read the chart. Any help would be great thanks.
Mike

It's very difficult to give you
definitive stats for a Princess-Cut,
save to say, stay below 80%
on both Table & Depth and look for
crown height starting at 10%+.Past this starting point, you must

We have found that superior light
output as measured by the BrillianceScope
can be achieved with various combinations
of Table/Depth percentages.
Ask for a Sarin or MegaScope analysis
for any Princess you are interested in.Good luck.Barry www.superbcert.com ------------------

Mike;
To be more specific:We have recently finished cutting
a suite of experimental Princess-cuts
with some very interesting results;
e.g.; a combination of 63 table/ 77 Depth
scored higher on the BrillianceScope
than a Princess with a 65/65 combination.The salient point is this:
Don't go into princess-cuts with
preconceived notions:[email protected]@K at stones.Barry www.superbcert.com ------------------

Mike, Barry is right, of course, you have to look at many stones yourself. However, I think AGA charts are a good start. As higher AGA class as higher chance for you to get a nicer looking diamond. Since there are no strict rules for grading fancies, one can find higher AGA cut grade diamond for less.Check out Oldminer’s post here: www.pricescope.com/ubb/Forum1/HTML/000068.html
