Pearl beads are small, spherical beads that are made from natural or synthetic materials that imitate the look of pearls. Natural pearl beads are made from real pearls that are harvested from oysters or other mollusks. Synthetic pearl beads, on the other hand, are typically made from glass, plastic, or other materials that are coated with a pearlescent finish to give them the appearance of real pearls.Pearl beads are commonly used in jewelry making, particularly for necklaces, bracelets, and earrings. They are available in a range of sizes, colors, and shapes, including round, oval, teardrop, and irregular shapes. The size of a pearl bead is typically measured in millimeters, with larger beads generally being more expensive.Pearl beads can be strung together on a thread or wire to create a piece of jewelry, or they can be incorporated into other jewelry-making techniques such as wire wrapping, bead weaving, and knotting. They can also be used to embellish clothing, accessories, and home decor items.
