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.
Maastricht silver
The oldest known piece stamped with the Maastricht hallmark is the so-called "arm of Saint Thomas", a 15th-century silver reliquary in the shape of an arm, now in the Treasury of the Basilica of Saint Servatius in Maastricht. Unfortunately, very little is left from this period. After the Siege of Maastricht (1579) the Spanish troops ransacked the city for three days and took anything made of gold or silver. Some silver chalices and monstrances from the 17th century have survived. With the arrival of the French revolutionary troops in 1794, the medieval trade system was discarded of and the guild of Saint Eligius dissolved.
