I have used a vintage optical lens glass monocle and painted it with purple paint and pale glow-in-the dark swirls. I then added iridescent diamond dust and sealed it with resin. Purple mountain jade beads and silver stars complete the design in a lavalier style. This comes with an 24 inch gunmetal curb chain.
