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 appearance, which reflects light in a variety of colors. This beautiful substance is composed of aragonite and conchiolin, giving it both strength and a unique luster. Mother of pearl is often used in jewelry, decorative items, and inlays due to its aesthetic appeal. It is also utilized in the production of musical instruments and buttons. The process of harvesting mother of pearl is sustainable when done responsibly, ensuring the protection of marine ecosystems.
