Bead
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 with a small hole for threading or stringing. Beads range in size from under 1 millimeter (0.039 in) to over 1 centimeter (0.39 in) in diameter.

Beads can be woven together with specialized thread, strung onto thread or soft, flexible wire, or adhered to a surface (e.g. fabric, clay).
In many parts of the world, beads are used for symbolic purposes, for example:
Beads are thought to be one of the earliest forms of trade between members of the human race. It is believed that bead trading was one of the reasons why humans developed language.[1] Beads are said to have been used and traded for most of human history. The oldest beads found to date were at Blombos Cave, about 72,000 years old, and at Ksar Akil[2] in Lebanon, about 40,000 years old.
After shaping, glass and crystal beads can have their surface appearance enhanced by etching a translucent frosted layer, applying an additional color layer, or both. Aurora Borealis, or AB, is a surface coating that diffuses light into a rainbow. Other surface coatings are vitrail, moonlight, dorado, satin, star shine, and heliotrope.
Tagua nuts from South America are used as an ivory substitute since the natural ivory trade has been restricted worldwide.
