I plan on re-cutting a 1.60 old miner''s cut into a RBC. Will the new stone be more brilliant than the old? It is an I color but faces up beautiful. I am also going to place it into a three stone ring with a princess cut on each side. Should I buy a pair of matched princess earrings and use those for the side stones? Also, what are the pro''s and con''s on white gold vs. platinum. Thanks for any advice!
