Here is a vintage Puka shell necklace. It is made of natural Puka shell beads in shades of white and cream. The necklace is 16 1/2" long. It is strung on a metal wire and has a barrel screw clasp. Puka shells are formed with a natural center hole or piercing, which makes them ideal for jewelry and crafts. They are native to Hawaii. The popularity of Puka shell jewelry emerged in Hawaii in the 1960s and 1970s, and there was a brief reappearance of the fad in the 1990s. This necklace is a classic.
