Vintage 30” Tumbled Stone(?) Multi-Stone Necklace

Vintage 30” Tumbled Stone(?) Multi-Stone Necklace in excellent vintage condition. This necklace has a barrel clasp with beautiful colored tumble stone (?) or could be glass (?). Very cold to the touch (not plastic of lucite). It also has gold-tone spacer beads. Amazing colors for fall. I’ve seen a very close match on eBay going for $400, I’m only asking $60. 30” total length including gold-tone clasp.
