Vintage Large Hawaiian Puka Shell Necklace

Vintage 1970s genuine Hawaiian puka shell necklace. The shells are a large hard to find size. They are 12.6 to 13.6 mm in diameter. The necklace is 22" long. The clasp is a costume grade barrel clasp with a few brown wooden beads on each side to help you grasp the clasp.

The necklace has 100% natural puka shells that are well matched in color and size.  These shells have natural holes, great wear from the ocean and sand and are bleached white by the sun. Surface has a high polish. Weight 135 grams. 

Look closely at the shells and you will see pale blue stains on them. It appears that they were worn with a blue denim garment the bled onto them. I started to polish this away and it did work, but my hands are too damaged from 22 years of computer work and I could not do the job. I am offering this at a discounted price hoping that you will have strong enough hands to restore these to their natural white color and luster.
