Jewellery
Jewellery (British English) or jewelry (American English) consists of small decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewellery may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal, often combined with gemstones, has been the normal material for jewellery, but other materials such as shells and other plant materials may be used. It is one of the oldest type of archaeological artefact – with 100,000-year-old beads made from "Nassarius" shells thought to be the oldest known jewellery. The basic forms of jewellery vary between cultures but are often extremely long-lived; in European cultures the most common forms of jewellery listed above have persisted since ancient times, while other forms such as adornments for the nose or ankle, important in other cultures, are much less common.
Thumb ring
Thumb rings have been in use in Asia since the Neolithic period. The first examples were likely made of leather, but artifacts made entirely of leather do not last thousands of years. Surviving artifact rings are made of bone, horn, or stone; presumably most would have incorporated a leather guard. Comparison with historical and modern rings shows little functional change over the millennia. In the cemetery of the small Rui state at Liangdaicun near Hancheng on the Yellow River (where it flows south between the provinces of Shaanxi and Shanxi), a Lord of Rui was interred in a tomb, M 27, dated to the eighth century BCE. His grave goods included two thumb rings, made of gold but of an entirely modern pattern.
