Solid gold. Stamped 14K Italy (see photos) Preloved solid gold herringbone necklace, in great condition, will last you a lifetime with proper care. 45 cm (17.75 inches) in length 3 mm wide I personally think this is the perfect size for a daily-wear herringbone necklace! Definitely makes a statement but still elegant and dainty for everyday styling. Perfect layering piece! Will be shipped in jewelry pouch. This listing is for the herringbone necklace ONLY. Please see my listings if you are interested in any of the other pieces styled with the necklace here!
