I just received a nearly one carat diamond from NUMINED as the center stone in my gorgeous engagement ring from my wonderful future husband. The diamond from NUMINED is absolutely breathtaking. There is no discernible difference between the NUMINED lab grown diamond and a more "natural" stone (I went into my jeweler for re-sizing after receiving the ring and she showed me natural versus NUMINED diamonds to illustrate). Seriously. I would have had no idea. Not only is the quality spectacular but buying a NUMINED diamond allowed my fiance to get a larger carat stone at a more cost effective price without sacrificing any quality. Plus, you are assured that the diamond is conflict free. I am beyond thrilled and could not give a higher recommendation!
