I've named these guys Skull Kings because the rhinestone spacers and silver plated bead caps look like a crown. I've also added orange and red acrylic flowers and Swarovski crystal round beads in fire opal to enhance the regal look. Kings should have jewels! The skulls are made of howlite stone and are turquoise color. The wire is silver plate and the earrings are attached to silver plated lever-backs. The earrings are 1 ¾ inches or 4.445 cm long. These earrings are perfect for Halloween and Day of the Dead, but people who love skulls wear them year round.
