Vintage Millefiori African Trading Bead Necklace 21 inches

This is a brilliant statement piece with seven Millefiori beads with brown and reddish wooden beads. It has a silver barrel clasp. 4th picture shows a shorter bead than the one opposite. I see a bit of stone damage, but it is not sharp. I also noticed that if it were the same size, the last seven beads would not fit. Perhaps this was intentional? The beads are 8 mm wide,the wooden beats are 6 mm, and the reddish beats are 2 mm. No markings. This item comes from a smoke and pet free environment
