What are imitation pearls made from?

Imitation pearls, also known as faux pearls, are typically made from materials such as glass, plastic, or shell. These materials are coated with a substance like nacre or a similar finish to mimic the luster and appearance of natural pearls. Some imitation pearls are also created using a process that involves layering materials to replicate the iridescent quality of real pearls. Overall, they are designed to resemble genuine pearls while being more affordable and accessible.
