Vintage 1970s Natural Hawaiian Puka Shell Necklace

Estate fresh 100% Natural Hawaiian puka shell necklace. These shells were bleached by the sun and tumbled by the Pacific ocean. Holes are natural as well. They have a few brown spots of color that the sun did not have time to bleach before they were collected. They are also an off-white color and very flat from being tumbled for a log time. 

They  are quite well matched and the shells are 4.9 to 9 mm in diameter. Necklace is 14 3/4" long and beads are on nylon. They were not professionally string and the clasp is a sewing hook & eye.

Super nice. Weight: 28.9 grams.
