Any kind of settings? Or are you looking for a setting for a particular stone? What kind of bands?
I have a couple of settings that are currently size 4.5 or slightly under, that could be sized down to 3.5. You can contact me through one of my DB listings if you're interested, and I can send you pics.
I have a lot of settings and bands in size 3.0 to 4.5 that have been sitting in my jewelry box. I have been thinking about doing some house cleaning since I haven't worn any of them since I got them. What exactly are you looking for?
