Gemstone of the Day - Chalcedony

Chalcedony is a catch-all term for cryptocrystalline quartzes (quartz with microscopically small crystals). The term "chalcedony" refers more specifically to semitransparent or translucent chalcedony with a solid color (commonly pale bluish-gray) and nearly waxlike luster. The color can also be white, blue, purple, pink, yellow, orange or red. Blue and purple are the most popular hues.

Chalcedony forms in rounded crusts, rinds or stalactites in volcanic and sedimentary rocks. The stone is extremely 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. Its earliest recorded uses were as projectile points, knives, tools and containers. 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. The stone is found in Brazil, Germany, Russia, the U.S.A., Canada, Africa, Turkey and Indonesia.
