I love my engagement ring, but I wasn''t being realistic when I asked for it. It is a three stone ring with center tanzanite, and two alexandrite side stones. Since I''m am ruining the center stone by wearing the ring(AAA+ picture doesn''t do it justice) I am looking into replacing it with a diamond. I like rounds and cushions(it is currently a round) but I''m assuming that the new stone would have to be the same size and shape as the original.
My question is this, what is the process I can expect when having the stone replaced? How much labor is involved from the jeweler? Will I have to go with a stone of the same size and shape?
Thanks for your help. I don''t want to go to a jeweler without some background as I don''t want to be taken advantage of.
