The Alfred Jewel is a piece of Anglo-Saxon goldsmithing work made of enamel and quartz enclosed in gold. It was discovered in 1693, in North Petherton, Somerset, England and is now one of the most popular exhibits at the Ashmolean Museum in Oxford. It has been dated to the late 9th century, in the reign of Alfred the Great, and is inscribed "AELFRED MEC HEHT GEWYRCAN", meaning "Alfred ordered me made". The jewel was once attached to a rod, probably of wood, at its base. After decades of scholarly discussion, it is now "generally accepted" that the jewel's function was to be the handle for a pointer stick for following words when reading a book. It is an exceptional and unusual example of Anglo-Saxon jewellery.

Cloisonné is an ancient technique for decorating metalwork objects with colored material held in place or separated by metal strips or wire, normally of gold. In recent centuries, vitreous enamel has been used, but inlays of cut gemstones, glass and other materials were also used during older periods; indeed cloisonné enamel very probably began as an easier imitation of cloisonné work using gems. The resulting objects can also be called cloisonné. The decoration is formed by first adding compartments to the metal object by soldering or affixing silver or gold as wires or thin strips placed on their edges. These remain visible in the finished piece, separating the different compartments of the enamel or inlays, which are often of several colors. Cloisonné enamel objects are worked on with enamel powder made into a paste, which then needs to be fired in a kiln. If gemstones or colored glass are used, the pieces need to be cut or ground into the shape of each cloison.
