What is a paste pearl?

A paste pearl is a type of imitation pearl created from glass or other materials that are coated with a substance to mimic the appearance of natural pearls. These pearls are often used in costume jewelry due to their affordability and can replicate the luster and sheen of real pearls. Paste pearls can vary in quality and are sometimes used in high-end jewelry pieces as a substitute for genuine pearls. They are distinct from cultured or natural pearls, which are formed by mollusks.
