Protection stone! 
 
Turquoise is perhaps the oldest stone in man's history, the talisman of kings, shamans, and warriors. It is a stone of protection, strong and opaque, yet soothing to the touch, healing to the eye, as if carved from an azure heaven and slipped to earth.
 
This blue-green mineral rock's name is French. The French word turquoise meaning is "Turkish stone." Treasured turquoise gemstones were transported from Asia, where turquoise rocks were mined, to Europe by way of Turkey.  Turkish soldiers attached turquoise stone amulets to their horses' bridles and saddles, believing that the blue-green mineral rocks would make their horses sure-footed. Turquoise was believed to protect the horse and rider from falling. This turquoise meaning caught on and eventually turquoise gemstones were worn to protect the wearer from falls, regardless of whether or not they were riding a horse.
