Vintage handcrafted long layered black & silvertone metal bead necklace

Great layered (4) longer bead necklace with the beads ranging from small at the top & getting larger until the largest ones are at the bottom (middle) of the piece. Between every single black bead is a silver & all are metal so high quality. Even the chain is high quality & very thin but tight box link & appears to be black. All the chains are connected in the back on its own side to its own O ring then to a large lobster clasp. What makes this piece very interesting is the chain that's used & that the beads hang low on the chain meaning it's about 1/3 chain to beads. On my display neck or hangs 13" - 16 1/2" Opened up end to end it's 31 1/2" - 34 3/4" Excellent - New condition
