This is my first time buying a diamond online from Blue Nile. I've done a lot of research and good light performance is important to me. I would like your input on this one diamond.

The numbers for this stone look half decent. Only thing i’m Not too happy about is the slightly thick girdle all the way around. The video on the BN listing also looks half decent as well. Not sure if BN will be able to get the vendor to provide an Idealscope image or not however.

I know these proportions individually meet the parameters recommended. That said I'd like to see the crown/pavilion angle combo be something more complimentary. Maybe a 35/40.6, 34.5/40.7 or 34.5/40.8.

Remember there are 8 crown and pavilion angles in a round diamond. GiA averages those and then rounds the crown to the nearest 0.5 degrees and the pavilion to the nearest 0.2 degrees.

That said pavilion depth is reported as 43% as opposed to 42.5% so perhaps the pavilions are all 40.6 or slightly better.

I'd like to see an idealscope or ASET image before committing but believe it has potential. See if BN will provide images.

Is there a cultural reason for such high clarity and color? Or are you willing to see options that are G/VS and larger? Just trying to understand your preferences so we can point you in the right direction.

Read up on Garry's BIC designation in hca.
Agree on the rest of your comments.

Potentially favoring brightness with nice fire in the right lighting and if it had a smaller girdle very nice spread but the girdle makes it a bit smaller.
But,
The gia rounding may be hiding issues so more info would be needed as sledge said.
