This faceted crystal bead necklace tests as rock crystal (a natural mineral, not man-made lead crystal). This strand in graduating sizes has knots in-between and a filigree, fish-hook clasp. You can wear this Art Deco jewel with just about anything, anytime and anywhere. Did you know that faceted crystal beads were popular in the Twenties because they reflect light and brighten the wearer’s face? Note that this necklace is a bit longer than most of its contemporaries in this style.
