I''m looking for a mounting for three stone round. Preferably with room for an 8MM center with 6MM sides. (yes, 4 carats of FANTASTIC BLING!). The diamonds are OEC (currently at GIA) so something with engravings are ok.. either 18KT yellow gold, or platinum (haven''t decided). I really like Dandi (?) "stuller looking" heads. Or something with hearts... Any ideas!??
