I have been shopping around since I posted last, and I have found a Tacori setting that I really love, but I have a question. After talking to some friends about the mounting, some of them mentioned that Tacori would only put a certain quality level of color and clarity diamond in their mountings. Now, I know that they only put a certain color and clarity in the sidestones and pave-set stones, but as far as the center stone that I select, what do they require, if anything? Do they require you to seperately purchase a certain quality stone before they will put it in your ring? Or will they put whatever center stone you want in the ring? I am confused.
