Vintage black faceted bead Charming Charlie statement necklace

Pretty solid black acrylic & faceted so that gives it a bit of light catching to sparkle already but it's also lined in-between all the beads with a tiny silver sparkly material being tiny crystals, a tiny diamond cut material, etc I'm not positive & I've put the piece under my 10-60x's mag light. I've come to the conclusion that it doesn't matter what it is, it's beautifully placed, there to stay & perfectly enhances the piece in the best way possible. This is a small - medium sized piece from top to bottom bead measuring 4 1/2" H x 4" at its widest points. It has a silvertone medium - large strong oval loop prettier but nothing fancy chain w/a larger lobster claw clasp. It can go as short as you want up to 20 3/4" New condition
