Jewellery or jewelry  is a form of personal adornment, such as brooches, rings, necklaces, earrings, and bracelets.

With some exceptions, such as medical alert bracelets or military dog tags, jewellery normally differs from other items of personal adornment in that it has no other purpose than to look appealing, but humans have been producing and wearing it for a long time – with 100,000-year-old beads made from Nassarius shells thought to be the oldest known jewellery.

Jewellery may be made from a wide range of materials, but gemstones, precious metals, beads and shells have been widely used. Depending on the culture and times jewellery may be appreciated as a status symbol, for its material properties, its patterns, or for meaningful symbols. Jewellery has been made to adorn nearly every body part, from hairpins to toe rings.

The word jewellery itself is derived from the word jewel, which was anglicized from the Old French "jouel",and beyond that, to the Latin word "jocale", meaning plaything. In British English the spelling can be written as jewelery or jewellery, while in U.S. English the spelling jewelry.

The modern jewellery movement began in the late 1940s at the end of World War II with a renewed interest in artistic and leisurely pursuits. The movement is most noted with works by Georg Jensen and other jewellery designers who advanced the concept of wearable art. The advent of new materials, such as plastics, Precious Metal Clay (PMC), and colouring techniques, has led to increased variety in styles. Other advances, such as the development of improved pearl harvesting by people such as Mikimoto Kōkichi and the development of improved quality artificial gemstones such as moissanite (a diamond simulant), has placed jewellery within the economic grasp of a much larger segment of the population.
