This mermaid dragon scale locket necklace glows in the dark with its magical glow, helping you express your inner mystery and whimsy. Choose your favorite hue – Blue, Purple, Rainbow, or Red – and pick from three metal finishes. Show off your unique look and be the envy of your friends! Beautifully crafted locket looks like a real Dragon Egg, Dragon Scales, Snakeskin, Mermaid Scales...you decide! Either way, this necklace is a show stopper. The real beauty of these "scale" cabochons is that they "magically" shift in color all depending on how the light hits it. Not only that, but they Glow in the Dark! GLOW IN THE DARK: We've used a very high quality long lasting glow mixture of blue which reaches full charge in about fifteen minutes of sunlight or strong florescent light (such as kitchen light or UV light---UV light will give a fast charging ultra bright glow). Gorgeous ice blue glow will diminish over time, but can be charged over and over again and will last for years and years. Glows brighter and longer than traditional glow powders or paints. MEASUREMENTS: 13x18mm Cabochon is set securely in a lovely vintage Victorian style locket. Locket is approximately 22x29mm or 1.25 inches in height x .95 inch width and holds inside photos at approximately .75 inches x .5 inch in size. Comes with a matching 18 inch link chain with lobster clasp. Add a mystical vibe to your look with our dragon egg and mermaid scale jewelry—perfect for cosplay, Halloween, or just for fun!
