Help, First time buyer!

[Flo_Rida]

So I am collecting information for a rock I'm looking at. This will be the centre stone of a ring I'm going to propose with.

I have attached an actual diamond image, ideal scope, and ASET image.

Ct weight is 1.29
Excellent cut, symmetry and polish according to GIA report
VS1
I color

Is this a good stone based on what you see?

Thanks for any help/guidance in advance!
