4mm Round Gemstone Bead - Blue Chalcedony AA (strand)

Chalcedony beads are a semitransparent or translucent (commonly pale bluish-gray) form of quartz, with a waxlike luster. Chalcedony forms in rounded crusts, rinds or stalactites in volcanic and sedimentary rocks. The stone is porous, so it takes dye easily and is frequently enhanced. Chalcedony has a slightly lower density and hardness than other quartz. Protect it from scratches, sharp blows, harsh chemicals and extreme temperatures.

Because of its abundance, durability and beauty, chalcedony was one of the first raw materials used by humankind. Seals were made from chalcedony in Mesopotamia as early as the 7th century B.C., and the Romans also adopted the practice. The stone was used in Renaissance magic for health and safety, and has been worn as carved cameos and gems for many centuries, especially popular in the Victorian era. In ancient times, it was used as a talisman against idiocy and depression. Today it is still believed to banish depression and mental illness, as well as fear, hysteria and touchiness. Chalcedony is also thought to reduce fever, aid eyesight, stimulate creativity and stimulate calm and peace.
