Sedef

Sedef is the Turkish term for mother-of-pearl, the iridescent layer that forms the inner surface of certain mollusk shells, such as pearl oysters. The substance is mainly composed of calcium carbonate crystals and organic matrix, producing a distinctive rainbow sheen. In Turkish usage, sedef also refers to the nacre itself and to objects that incorporate it.

In Turkish decorative arts, sedef is widely used in inlay work known as sedef kakma. Thin sheets or fragments of nacre are cut and set into wood, metal, or horn to create intricate patterns. Sedef inlays are found on furniture, boxes, jewelry, and musical instruments, often featuring geometric or floral designs. The technique highlights the luster and color variations of the material.

Culturally, sedef is associated with traditional crafts in Ottoman and broader Middle Eastern artistic contexts. Objects described as sedef typically indicate the presence of nacre or a nacre-like surface, valued for their delicate beauty and durable sheen.

Given name: Sedef is a common feminine given name in Turkish-speaking communities, drawing from the material’s symbolic associations with beauty and refinement. People named Sedef appear in various professional fields, particularly the arts and public life.
