Glow-in-the-dark jewelry is a type of accessory that emits light in the dark after being exposed to a light source. This effect is achieved through the use of special materials, such as phosphorescent pigments, which absorb light and then release it slowly over time. Common items include necklaces, bracelets, and earrings, often made from plastic, resin, or glass. These pieces are popular for their fun and unique appearance, making them ideal for parties, festivals, or nighttime events. They come in various designs and colors, allowing wearers to express their personal style while enjoying the captivating glow effect.
