Hematite Square Design Beaded Eyeglass Chain~~NEW 28 inches. This Beaded Eyeglass Chain is hand made from iridescent grey 11/0 glass seed beads. The Hematite beads are placed at 3-4 inch intervals. The Square bead is 1/2 inch across. The photo does not do these beads justice!! Hematite: a glamorous gunmetal glow. Hematite is the mineral form of iron oxide and has a striking metallic luster, similar to polished metal. The hand beaded chain is 28 inches long and has black elastic fancy loops to attach your glasses. I can make my chains any length, just ask!!! The chain drapes beautifully. It has a delicate appearance and is strung on nylon coated cable for super strength!! The chain is light yet strong. Each end has a wire guardian to protect from breaking. Both ends are secured with double crimps and covers for beauty and comfort. Hand made by me in the USA!!
