Genuine Hawaiian Puka Shell Necklace

Vintage 1970s Hawaiian puka shell necklace. This piece has a mix of different grades of shells from natural worn to shells that were chipped away by hand to make them smaller and dish shaped. Most of the shells still have the brown stripe colors as they did not lay iin the sand long enough tp bleach. I am sure that this necklace was made late into the Puka craze when orders of these could not be filled fast enough. It does have merit as it is pretty and the shells are graduated. It is 18" long which is nice too as many of them are 15" choker length. Truly a vintage piece in original condition. Found in Venice Beach, CA.
