Hello,

After a brief hiatus, I am back and continuing my search for new diamond earrings. Thanks to your help in my initial post, I feel I have a better starting off point.

At the moment I am interested in feedback about this tool.

https://www.pricescope.com/tools/AGA_NAJA_Cut_Class_Grader

I understand that cut is most important for how brilliant a stone performs, but I am having difficulty understanding the parameters for this tool. I have run the specs from a handful of Whiteflash ACA and Blue Nile signature Ideal stones and ALL of them are coming up as 3A. Is this okay? What number range should I be looking for within this tool. Or is this tool not that useful within the context of the idealscope?

Thanks!

Looks like they want the crown angle in degrees and pavilion angle in percent. Are you sure you are entering percent where they
want percent and degree where they want degree?
