I AM PARTING WITH A FEW OF MY VINTAGE PUKA SHELL NECKLACES.  THIS ONE IS HUGE, HEAVY AND LONG.  IT MEASURES APPROXIMATELY 20 1/2 INCHES IN LENGTH AND FEATURES THE ORIGINAL BARREL CLASP.  I AM NOT SURE OF THE AGE OTHER THAN IT IS NOT NEW.  THE WEIGHT ON THIS PUPPY IS 210 GRAMS WHICH IS THE SAME AS 7.4 OUNCES.  PLEASE REACH OUT IF YOU HAVE ANY QUESTIONS.  THANKS.
