Has Anyone Compared Different Two-Stone Ring Collections?

I've been checking a few jewelry websites and noticed that every brand offers something different. Some have only a few designs, while others have a much bigger selection.

If you've compared different stores, what helped you decide where to buy? Was it the design choices, pricing, or something else?
