I''ve seen a number of posts talking about diamonds that "face up" smaller than their carat weight. These comments seem to be based on a combination of the depth and diameter of the stone. Maybe I''m not looking in the right place, but is there somewhere that suggests an appropriate diameter per carat? Or is this more based on depth or a combination of depth and girdle thickness?? What is the best way to figure this out? I don''t want a particularly big stone (def. 1.5 ct or less, probably closer to 1), but it would be nice to get something that looks at least the size that is being paid for, rather than smaller.
