Smooth stone disks of denim-blue lapis alternate with silver in a short necklace with style for a man or a woman. There's a rhythm to this design that keeps on coming: Silver, Blue, Silver, Blue, Silver, Blue, all the way around to the silver clasp. Studded silver-plated metal beads have a goth aesthetic. Magnetic clasp is easy-on, easy-off. Length at 18 1/4 inches (46.5 cm) makes it a choker or a collarbone grazer depending on the size of the person who wears it. Blue beads are 6 mm in diameter and 3 to 4 mm thick; metal beads are 4 mm around, which keeps their pointy studs tucked cleverly inside the stones. A good choice for casual wear, out clubbing or beaching.
