You can't tell by numbers alone, but I don't see any BIG red flags, just small ones. I typically like the depth to be 59-61.9. Also the pavilion angle is slightly high for that crown angle. An ideal crown angle of 35 is best suited with a 40.6 - 41 pavilion angle on the GIA rounding scale. Is it pretty though? Have you seen an ideal scope image?

Whats the girdle, cutlet, and crown/pavilion height?

I wouldn't buy it.
It is not cut well enough since it scores over 2.0 on the HCA.




Good cut is much more important than color or clarity for a diamond to look beautiful and perform well with light.

Here's how to select a well-cut round diamond.
Get the following four numbers from the lab report and enter them into the HCA (Holloway Cut Advisor):

Depth %
Table %
Crown angle in degrees
Pavilion angle in degrees

Here's a link to the HCA: https://www.pricescope.com/tools/hca

Reject rounds that score over 2.0.
If it scores under 2.0 the next step is to get an Idealscope image. https://www.pricescope.com/tools/ideal-scope

Compare it to this reference chart: http://www.ideal-scope.com/1.using_reference_chart.asp
