A vintage 1/20 12K yellow gold-filled black and white glass cameo pendant necklace. The cameo depicts the profile of a young lady in a right-facing profile on white glass attached to a high polished black glass oval-shaped background bezel set to a decorative open-back frame. The pendant measures 1.72" x 1.01" and comes on a twisted chain necklace that is 18" long. The cameo has a mark on the back, please see zoom-in images for more on its condition. Both the necklace and the pendant are hallmarked 1/20 12K GF. The pendant has a maker's mark that is hard to read. Thanks!
