Worth $400.00 from Helzberg's. This is authentic, yes! No worries about quality. I simply don't really wear jewelry enough to need it. Might not be the original chain, can’t remember. Sometimes I exchange the chains for a longer ones. (Crafted from 10K white gold, this whimsical butterfly pendant is adorned with pear-shaped lab-created opals, pear-shaped blue topaz, and round single cut diamonds.)
