Mother-of-Pearl is a natural material produced by certain mollusks, such as oysters and abalones. It forms the inner layer of their shells and is known for its iridescent appearance, which reflects light in beautiful colors. This unique luster makes it a popular choice for jewelry, decorative items, and inlays. The term "mother-of-pearl" also refers to the smooth, shiny surface that results from the layering of aragonite and conchiolin, which are minerals secreted by the mollusks. This material is often used in crafting items like buttons, watch faces, and musical instruments, adding elegance and beauty to everyday objects.
