Mine is a .75 on a size 7. I suggest going to the under 1 carat thread: link I know there is another size 7 thread but I don''t remember the link. I''ll try to find it for you.
thanks so much. i just want to have a reference. it is such an expensive purchase i want to make sure i dont have second thoughts. all your rings were so beautiful, i hope that mine can be near as lovely as yours.
