*Update*
After thinking about it for awhile, I decided to start from the beginning and think "What do I really want?". I knew I wanted a Wink stone, but I was wavering about what type of ring I really wanted. I realized I don't have a nice solitaire in my collection, but I have several WG diamond bands that would look nice with one. I just fell in love with the idea of having a classic solitaire but with a twist, a large OEC stone instead of the usual RB. I also realized if I'm going to be spending several hundred dollars, I might as well just spring for the gold instead of SS so I can have a "forever" ring.
I found a setting that is not only what I want, but within my budget...just a 6-prong WG solitaire from e14k.com:

I'm going to add the comfort fit option.
I feel really good about the decision and ready to move on with the project.
The only question marks I still have are:
A) Should I go for the 4ct. (10mm) or 5ct. (11mm.)? I want something big, but I'm not sure if the 11mm would be too big. I don't know. I considered the 3ct. size (9mm) as well. But I have several 8mm rings already and kind of wanted to go the extra mile with this one, have it be special. I'm leaning towards 5ct, I think. All sizes would be within budget.
and B): Should I do Light Yellow or Imperial White? Ideally I would like it to be J/K in color. H (Imperial White) would be OK too. I'm just not sure what color on the scale the Light Yellow compares to.
