Other than tradition, there’s really no reason that jewelry has to be made from precious metals and gemstones. Personally, I’d rather wear one of these slick glow-in-the-dark rings, fabricated from carbon fiber.
Israel-based Composite Corporation handmakes these rings using carbon fiber and composite materials, along with epoxy resin, and a special phosphorescent powder. The resulting pieces look super cool day or night. When the lights are on, you see that sleek and technical carbon fiber texture, when they’re off, they glow quite brilliantly.
The rings’ makers don’t specify how long you need to charge them, or how long they glow, but there are phosphorescent powders out there that can last anywhere from 15 minutes to 15 hours, depending on the color, so I’m guessing the same applies here. Greens have a tendency to glow longest, followed by blues, with yellows and reds having the shortest glow times.
They’re available in a variety of designs and colors over on their Etsy shop, with prices starting at $79(USD), and each one can be custom ordered to your exact ring size.
