bead (redirected from getting a bead on)

bead

Small object, usually pierced for stringing. It may be made of virtually any material—wood, shell, bone, seed, nut, metal, stone, glass, or plastic—and is worn or affixed to another object for decorative or, in some cultures, magical purposes. The earliest Egyptian beads (c. 4000 BC) were made of stone, feldspar, lapis lazuli, carnelian, turquoise, hematite, or amethyst and were variously shaped (sphere, cone, shell, animal head). By 3000–2000 BC, gold beads in tubular shapes were in use. From the Middle Ages to the 18th century, trade in beads was enormous. Today the richness of beadwork varies with fashion.
