Faux Turquoise Black Necklace Knotted Bead Rolo Chain Antique Silver Tone

I bought this necklace in early 2000 and wore it a couple of times. Since then, it's been safely locked away in a jewelry box. The knotted beads are a light turquoise color and the textured large link rolo chain is antique silver toned.
