Turquoise Crystal Chakra Choker Necklace Double Layered Length is 35cm + 3cm ext. Pendant total length is 4cm. 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.
