Necklace silver with black stones 52"

Very cool necklace that can be worn different ways since it's 52". No clasp. 3 black stones - could be onyx - elongated 4-sided, hexagon sided and round ribbed are alternated with metal top-shaped beads and black beads with silver flecks along with 4 black and gray patterned stones of different shapes. Connecting them are silver chain links. Very sleek.
