Question - AGA Cut Charts (radiant cut)

[rcktsci]

Hi,
I am learning about diamonds so i can buy
her the "rock" and feel confident that I got
something good and what i paid for.

The website is great.

On the AGA Cut Charts for emerald/radiant on the
website, there are two set of percentage #''s under
a column. (left column under tutorial)

Like Column Class 3A for Table % :

69.1-74.0
57.9-56

I understand the measurement, but what are the
two sets of ranges?

Second, question what is the suggested aspect ratio,
(length/width) for a radiant in general, or in the US?
The chart mentions #''s but does not really give a
lot of background to understand them.

I know she wants at least a 1.25 aspect ratio.

thanks

Um, I'm too lazy to look right now, but I remember there was a less than a certain carat and greater than carat.

As to ratio, it's really a matter of personal preference.

Did anyone ever get back to you on your questions? I have the same two myself. Unfortunately, I see your psoting is quite dated. Am hoping you might have been informed by now.
