I''m looking to remake my engagement ring and am exploring several different settings. One I''ve always loved is the Tiffany three stone style with the pear shaped side stones. Can you purchase only the ring and side stones and have Tiffany use an existing center stone? I have a rather modest sized .8 carot stone and would like .25 carot side stones. Does anyone know of a similar ring by another designer? I love Tiffany''s style but don''t necessarily need the name and extra cost. Thank you!
