Bracelet, also known as "hairpin", "bracelet" and "arm ring", is a ring-shaped ornament worn on the wrist. Besides gold, silver and jade, it is also made of rattan. Bracelets have a long history and originated from the transition from matriarchal society to paternal society. According to relevant documents, both men and women wore bracelets in ancient times, with women as a symbol of marriage and men as a symbol of status or the nature of work. Besides, in ancient society, people believed that wearing bracelets could ward off evil spirits or meet with good luck. In the late old days, the fact that humans wore decorations has been confirmed by many unearthed objects at home and abroad. In the statue of Venus unearthed in Willendorf, bracelets and other ornaments are engraved on the wrist. In the bone carvings unearthed in Ituriz, there are also ornaments similar to bracelets. Among the objects unearthed in Maijin, Ukraine, there are exquisite bracelets with decorative patterns carved by mammoth ivory. Among the objects unearthed in Grimadi on the Riviera coast, besides bracelets made of fishbones, there are bracelets made of shells, oyster shells and animal teeth.
