I'm looking to create a 3 stone RHR utilizing 2x .30 transitional side stones with a gemstone center stone in the purple/magenta color family. My first question is whether or not these two shapes will work well together. My second question is if stuller is a good brand to consider or if there's another brand/vendor that might be worth speaking to. I'm hoping to keep this project somewhat inexpensive since this ring will serve as an occasional RHR.
