Gold tone herringbone chain bracelet

Gold tone herringbone chain bracelet. Unsure but I think it is gold plated. Because there is no tarnishing despite it being pretty old. Unsure of metal content. Beautiful bracelet, perfect for charms or stacking or wearing alone for a dainty look. Stamped Korea. Consider a bundle of jewelry to save on shipping - I have a lot of very old antique and vintage and retro pieces in my closet. Thanks for looking.
