1970s Liquid Silver Puka Shell Necklace

Vintage 1970s Hawaiian puka shell necklace in a Southwestern style. It has sterling liquid silver beads, brown heishi and two turquoise beads. Original brass barrel clasp. 18" long. The liquid silver beads look like they may have a gold wash that was worn in places. Has some tarnish. Will polish up. Pukas are natural and bleached white from the sun. They are pitted from tumbling in the sea.
