Authentic sterling silver - purchased by me at the Tiffany & Co. store in Michigan sometime in the late 2000’s or 2010’s. Silver is still bright but would benefit from a professional polishing. Light dainty chain. Too small to easily capture in photos but the clasp does have the Tiffany & Co. 925 tag. Will come with box and silver bag. However, I don’t think this is the bag that the necklace came in. Approximate measurements: 1 inch pendant 9 inch chain drop 10 inch - entire necklace length
