First, thanks Diamondseeker for replying to my earlier post. Unfortunately, the head cannot be changed b/c it is integrated. Does anyone else know if it is ok to place a 1ct stone into a 2ct head (that will be modified to fit)? Again, the head is integrated so it cannot be changed out, only modified. I am thinking about just ordering a new setting made to fit a one carat, but how do I know what it is made for? Most vendors that sell the plain Tiffany style settings w/ an integrated head don''t state what size diamond it is meant for or they give a broad range like .5 to 3 carats which makes me think it would be fine for my current jeweler to just modify the head afterall. Do most settings just have a generic head that can be modified to fit any stone? Please help...so confused. Thanks!
