Mookaite Jasper beaded Necklace With Yellow Center Bakelite Bead

This necklace appears to feature Mookaite Jasper beads and a large central bead, I'm thinking Bakelite. This necklace is very very heavy! The picture literally doesn't do it justice. The colors are so pretty. *full disclosure* it looks to me that the clasp has been replaced. This is out of my own collection that I'm selling, so it never bothered me. But let me express again how heavy this necklace is lol and cold brrrr
