I think it depends on how you set them. The dimensions of a 1 ct princess are roughly comparable to a 3/4 ct round, and they are cut deeper than rounds. However, if you turn the princess 45 degrees so the points are N/S/E/W oriented and measure the ''diameter'' as the distance from corner to corner (diagonally), it will appear a lot larger. The other issue is that most princesses on the market are cut poorly and don''t reflect light from corner to corner, making them appear smaller than they are.

remember, when comparing the area of a square to a round it''s like comparing apples to oranges. the diameter of a round compared to the same carat weight princess will always be bigger due to simple geometry. when comparing areas of both you ALWAYS need to keep in mind that a square has area (compared to a circle with same diameter) in its corners.
anyhoo, i have a .85 carat princess (5.17 x 5.42 mm) and after doing some area calculations, i discovered it''s of the same approximate area size of a .80 carat round, so yes generally speaking, the same carat weight round has more surface area than a princess but not to a wildly disproportionate level. now, how one''s eyes sizes up a square to a circle can totally be misleading. it really is hard to tell.
the area of a circle is pi*r squared (3.1412 times radius squared). this does NOT mean that a circle with the same dimensions as my 5.17 x 5.42 princess is the same (otherwise that would be the size of a, maybe, .60 carat round?... which it isn''t).
pheww. i''ve probably confused y''all!

I''m also a fan of the starset orientation.
Ok, I may be asking a silly question here, but why not put the round (if that''s what you end up with) in a round halo setting? Are you striving for/wanting a total cushion look?Date: 7/24/2009 10:41:47 AM

Thanks for all your posts!
Ellen that was really helpful. I def want to put the stone in a cushion shaped halo. I''m also looking at cushions but the thought of rounds having more spread and more brilliance is leaning me towards them. I''m just scared that you can tell that it''s a round in a cushion (gaps/spaces).
