Vintage 12 karat gold filled choker necklace with faux pearls

One of a kind vintage 12 karat gold filled choker necklace. Quite beautiful. 15" long. Stamped 1/20 12K GF on the ring adjacent to the clasp. It means that 20% of the total metal weight is real 12 karat gold. With faux pearls of light gold color. Some of them have signs of wear, as pictured. These are not too obvious due to the design with busy pattern, and the necklace looks quite nice. Vintage gold filled jewelry is considered valuable and collectible as it tends to be well made and is covered with a thick layer of real gold.
