Internal Diamond Proportions ?

[makisupa]

Unfortunately, most dealers don't have a report with their loose stones that grades the brilliance. I'm currently looking at a diamond that is AGS000 and I have seen it under a hearts and arrows scope. Needless to say it looks good under the scope. My problem is I can't tell a difference in brilliance unless it is drastic. Do most stones with an ideal cut usually fall into an acceptable level of brilliance or are there a good proprotion of ideal cut diamonds with poor brilliance? To my eye, they all sparkle.

Thanks,

Rob

Hi Rob,

to check whether the diamond is not steep/deep.


I guess you already did it and got 1.1 HCA, wich is perfectly fine for the stone with AGS0 report.

Thanks Leonid. What I was getting at though was looking for a way to understand whether or a diamond "sparkles" as well as it should. I read up on having a light test done in order to measure the diamonds brilliance by testing it against white and colored light. So I guess my question is do diamonds with a AGS000 cut generally rate high under a lightscope test or is it hit or miss?
