Flashy Australian Boulder Opal Necklace "Enchanted Bridge"

This interesting little Opal pulses between a hazy scene with blue flashy flecks to a full on curtain of electric green with cobalt flash.  The cream 'boardwalk' always remains.  Such a cool piece!  It is framed with a gold colored bezel and a  14 kt gold fill ring with a silver top ring.  The sterling chain is 17" in length.  One of a Kind.
