Elegant Crystal/Black Drop Detail Necklace

Clear/black crystals with silver hardware. The entire chain has crystals. Adjustable length with lobster claw closure. The stones have beautiful shine/sparkle! This necklace is beyond stunning! A touch of tarnishing on the under side. Fairly certain this is vintage. Length measures 11.75 inches to 15.5 inches lying flat (it doesn’t lie completely flat where the drop happens, the chain curves to that)
