An enamel charm is a small decorative item typically made of metal, with a layer of colorful enamel coating on the surface. Enamel is a type of glass that is fused onto a metal surface through a high-temperature firing process, resulting in a smooth and durable finish. Enamel charms come in a variety of shapes, designs, and colors, and are often used as adornments for bracelets, necklaces, or keychains. They may feature intricate designs, symbols, or images that have special meaning or significance. Enamel charms are popular among collectors and make lovely gifts for those who appreciate unique and personalized accessories.
