Hi everyone! I have a quick question and that is whether you can re-cut a GIA reported round diamond. The reason I''m asking this question is b/c I was given one to mount on an engagement ring setting from my mom, but the ring doesn''t really sparkle. I went to a dealer and saw that their diamonds yielded more cuts and thus sparkled a lot more. The sales told me that all the color and clarity is not important but the the most important element is the cut. So is it possible to have the dull diamond re-cut or would I be better off buying a new diamond. I hope this makes sense. I''m still new to this. Thanks for all your attention and help!
