Hi everyone! I''ve been lurking for awhile now and have found this website so informative!! I am hoping the experts here can help me with a question. I am setting my 1ct round brilliant into a new Tiffany style setting. The jeweler has a stock piece that is made for a 2ct, but they said they can modify it to fit my 1ct stone. Although this is a very common setting, it is the last setting that they have of this sort. It has the integrated head. Now they are only going to carry ones with a peg set head which I do not like at all. I cannot order from another vendor b/c it will void my diamond warranty if I don''t use a setting provided by them. So my question is...is it ok to use a setting intended for a 2ct round diamond for a 1ct round diamond? What implications does modifying the head have as far as appearance/security, etc or is this really no big deal? The jeweler said they always have to modify the head to fit each unique stone, but shouldn''t you start out with something closer to the right size? Thanks for any input!! I''ve become addicted to this site!!
