3 layer floating all glass beaded necklace on silvertone wire in shades of green

This is a gorgeous 3 tier layered floating necklace with all glass beads in shades of green on silvertone metal wire. The large rectangular semi-translucent art glass beads are dark green with lighter swirls inside. The faceted glass rondelles are a translucent light green. She measures 18” inches long on her shortest layer plus a 2.5” inch extender. She has a lobster claw clasp and is unsigned. Very good pre-owned condition with no flaws noted.
