Unfortunately the report for this stone is too old, dated 2002, before GIA even starts to measure angles, so we have no way of knowing roughly how well it is cut.

EDT:
Actually, from other numbers, M-VT girdle, G symm, sounds like not very well cut. The only way to know is to view it with an IS/ASET scope. Get it send to an independent appraiser before confirmimg purchase?

Hi Rosebud,

Here's a link to the report:
http://www2.gia.edu/reportcheck/index.cfm?fuseaction=home.showReportVerification&reportno=12434887&weight=0.90

Since it was graded in 2002 there are no crown and pavilion specifics. Two flags are the very thick girdle and the comment on the report stating that 'crown angles are less than 30 degrees.' With the indicated mm measurements, table size, depth and girdle data we can deduce that the pavilion angles may run anywhere from near 40.9 degrees (30 degree crown) to 42.0 degrees (26.5 degree crown) or even higher - and that's a stab in the dark.

A current 3D scan, IS or ASET photo would tell us more, but be aware that the highest cut grade GIA would give this diamond today is 'Good,' and it could be lower depending on crown angle and pavilion angle specifics.

Thanks so much stone cold!! =D You are a great help!

I figured I would need to get more info, but I wanted to check to see if someone knew more tricks than me... all I know how to do is punch numbers into hca.. lol! That is a great conjecture though about the cut, I will try to find out more information!
