Boho Handmade Rough Stone Necklace

Handmade Pendant Necklace (purchased from Etsy a few years back). Not sure what the stone is-agate or howlite(?) Raw smooth stone (about 154 cm) with 2 different types of antiqued brass chain. Makes it extra unique. Total chain length: 14” with Lobster claw clasp. All items I ship get packed in recycled materials and packaging. Not as pretty, but trying to be kind to the planet 🙏🏻🌱
