Projection necklaces work by using a small, convex lens or transparent stone embedded in the pendant to project an image or message when light passes through it. Typically, the image or message is microscopically engraved on the inner surface of the lens or stone, and when light, such as from a flashlight or phone, shines through the lens, the image is magnified and projected onto a surface. These necklaces often feature sentimental images or personalized messages, making them popular as unique, meaningful gifts.
