Authentic Navajo Antique Heist Necklace 14” with Sterling Sikver Clasp Genuine Turquoise, onyx, and Polka Shell strung in a strong rope. It’s lasted 100+!years and still has so much strength !!! Antique as in. yes, over 100+ years old. Super Cute Unisex You can see the age in the Heishi & Polka Shells, but this gives the necklace more characters. It in no way looks “too old” “gonna break” or “tired” I bought this about 5 years ago from a local antique store I frequent.
