This is a beautiful vintage 1920s or 30s Bohemian Garnet festoon necklace. I am not sure if these are genuine garnets, or just glass. My experience is that genuine garnets are usually set in silver or gold. This necklace is gilded brass, with most of the gold wash worn off the backs. The back is also marked in a circle "Pat No" with some small numbers. The clasp has a garnet colored stone as well. The necklace measures 16 3/4" long, and the center part measures 4 3/4" by 1 3/8" at the center. There are no missing stones. There is a light spot of discoloration to the brass metal on the back of the center oval. This is a very elegant necklace.. you will love it.
