Vintage Silver single pearl necklace 16 inch

Very elegant piece. I am not sure if this is Pearl. It looks and feels different than the fakes, but I’m no pro. Belonged to my aunt, vintage from the 70-80s. 16 inch silver chain with hook clasp. Please see photos carefully as this is the exact item you will receive. Let me know if you have any questions. May have tiny scratches from wear but in good condition.
