Beads are known to be one of the earliest forms of trade between the human race. It is thought that is because of bead trading that humans developed language. Beads are said to have been used and traded for most of our history. The oldest beads found to date were at Ksar Akil, in Lebanon. Prior to this find, the beads found in the Blombos Cave were the oldest at about 72,000 years old.

A bead is a small, decorative object that is formed in a variety of shapes and sizes of a material such as stone, bone, shell, glass, plastic, wood or pearl and that a small hole is drilled for threading or stringing. Beads range in size from under 1 millimetre (0.039 in) to over 1 centimetre (0.39 in) in diameter. A pair of beads made from Nassarius sea snail shells, approximately 100,000 years old, are thought to be the earliest known examples of jewellery. Beadwork is the art or craft of making things with beads. Beads can be woven together with specialized thread, strung onto thread or soft, flexible wire, or adhered to a surface (e.g. fabric, clay).
