|Miracle beads are made of layer upon intriguing layer to create a bead that seems to glow from within. First, you have your lucite core. Then there is a mirrored silver plated around that. Next, there are layers of lacquer. The result: a bead that, when the light hits it just right, miraculously seems to exude light. 12mm miracle beads are the largest size we offer and are perfect for bold, oversized jewelry designs.
