My first ring was a trendy antique looking pave style setting. I found I tired of the style quickly and all the pave stones snagged on everything and scratched my son. I have a trellis style setting for my solitaire now and a channel set wedding band. I like the trellis style because the band is a bit on the wide side and it doesn't look odd on my long fingers. I also like that there is enough substance to the band of the ring so that it isn't top heavy and it's not always spinning around on my finger. A cathedral mount might work for you also.
If the stone is an heirloom, the edges of diamonds weren't as polished years ago. I don't know if this would create a problem if you opted for a bezel setting or not. Personally, I think you need a larger stone for a bezel setting otherwise the stone gets lost in the setting.
Find out what size stone it is and hit the stores, even at the mall, and try on some rings. Even Kay's will sell just a mounting and mount the stone for you. Jared does most of their repair work anyway.
