Tri-strand tiered necklace, faceted black acrylic shapes along silvertone chains

This is a really pretty three strand tiered necklace featuring faceted acrylic black beads shaped like squares and balls along silvertone chains with tiny black accent rhinestones. The faceting on the squares is finely done like a checkerboard, adding lots of sparkle. She measures 17.5” inches plus. 3” inch extender. She has a lobster claw clasp and is unsigned. Lightweight. Very good pre-owned condition.
