Help finding cushion e-ring with ~15k budget

[champagnepowder]

Hello:

If I had hair I would probably be pulling it out right now or it would definitely be turning grey!
I thought I had a ring pretty close to picked out but I have looked through several posts here and feel like I
could find something better (quality and price) with your help. I am trying to do this in secret (sorry but the element of surprise is important here) and all I really have to go off of are some pinterest photos my girlfriend saved. I have attached those photos and would like help finding the best cushion possible (best cut, color from D-G, carats 1.7 or higher).

This site has been a great learning tool so far and I appreciate any help you can provide!

Have you discussed anything with her previously? How do you know she wants a cushion? The last photo is actually a round stone in a cushion halo. So does she want a cushion STONE or a cushion SHAPE overall?

Yes, I understand the last photo is round. I was just providing some examples of photos she saved.
She likes the cushion more so the cushion shape is what I will be going with. Thanks for asking for
clarification.

Great, just wanted to make sure. And is the 15k for the stone only or for the setting as well?

The 15k is for the stone only. Thanks!

eta - also this one. Not sure how it would perform (slight bowtie) but the shape is heavenly
