Permanent jewellery is a type of jewellery or adornment that is worn continuously for a significant period, and is designed to be difficult or impossible for the wearer to remove at will. Unlike piercings, which involve permanent or semi-permanent body modification and are removable but are often continuously worn, permanent jewellery is fitted around a body part so it is impossible to remove without being broken or unfastened with special tools. Permanent jewellery has held cultural, religious, and social meanings since at least the 11th century BCE.
