Fine Hawaiian Puka Shell Necklace Larger Size Vintage

Wonderful vintage Hawaiian puka shell necklace.  The necklace has 100% natural puka shells that are graduated in size from 5.6 mm in diameter to 13.8 mm in diameter. (Measured with caliper) It is on original beading line and it is strung very tight, almost too tight. Makes then necklace feel stiff. It would not hurt to restring them. I just like to leave things original as found. 

These shells have natural holes, great wear from the ocean and sand and are bleached white by the sun. 

Necklace is 17 1/4" long. Weight: 95 grams. Fine, collectible and valuable necklace.
