I''m wavering about what size carat to go for with my girlfriend''s engagement ring. Since i haven''t had her try any on I really don''t know how they will look, but i do know that she does have pretty small hands (size 4), and she wants a thin band. I want it to "look" like it''s at least 1 carat to the casual observer, so I''ve been thinking about a .9 carat. But I''m also thinking of expanding my budget and going larger. What about a 1.4-1.5, would that look just way too large and flashy on such a small hand? I certainly wouldn''t want to shell out the extra money if it makes the ring look too out-of-proportion or ostentatious.
