A dealer mistakenly set my diamond before I had a chance to re-inspect it before purchase. I think i''d like to re-inspect the diamond alone anyway and possibly get it appraised. Will unsetting/re-setting negatively affect the diamond or prongs at all? i.e. will it weaken the prongs or make them look "worn" or even damage the diamond? Or is unsetting/resetting a common and easy thing to do with rings?(I''m a novice if you can''t tell.)
