Heavy artisan carved green ocean jasper necklace

This is a heavy necklace and I’m not quite sure what the stones are made of but it’s big. Green agate, ocean jasper or maybe even some sort of jade in large carved beads and polished disc beads with matte goldtone large spacer beads. Silky corded necklace. This piece is from my mother in laws collection and she loved wearing this hefty necklace. See pictures for details and approximate measurements If anyone can identify the stones please let me know. It’s a funky and amazing necklace Ask any questions🙋‍♀️ Bundle for extra savings🛍🚐 Happy Poshing❤️🐾🐾🚐 A148
