Chunky Horseshoe and Medallion/ Charms Cowgirl Necklace

Chunky Horseshoe and Medallion/Charms Cowgirl Necklace. Super unique and large necklace, silvertone, not sure what it's made of metal or material. Unique and has some tarnish and has a rougher look as shown in photos, does really give it character. Please review pictures carefully for condition and approximate measurements. Let me know if you have any questions. J2
