I am upgrading my ring for my 20th anniversary. I plan to get a 3 carat stone, either radiant or cushion. I like the rectangular shapes of either of these stones, as opposed to the square. I will be using either trapezoids or bullets for the side stones, and the ring will be set in platinum. Any opinions on cushions vs radiants? I will be purchasing a GIA H SI1 stone, as that''s my price range. Does anyone have any pictures of a radiant or a cushion, with either trapezoid or bullet sidestones? Any opinions on which would be prettier, more sparkly, etc? Thanks. Joy
