Mother-of-pearl, also known as nacre, is a natural material produced by certain mollusks, such as oysters and abalone. It forms the inner layer of their shells and is known for its iridescent sheen, which displays a range of colors depending on the angle of light. This beautiful substance is composed of aragonite and conchiolin, making it both strong and lightweight. In addition to its aesthetic appeal, mother-of-pearl is used in various decorative items, jewelry, and inlays for furniture. Its unique luster and durability make it a popular choice for artisans and craftsmen. Mother-of-pearl has been valued for centuries in many cultures around the world.
