Chrysocolla exists in various shades of blue, turquoise and green. It is opaque, often banded and most commonly seen as a tumblestone.
It treats arthritis, bone disease, muscle spasms, the digestive tract, ulcers, blood disorders and lung problems. It detoxifies the liver, kidneys and intestines. It re-oxygenates the blood and the cellular structure of the lungs, and regenerates the pancreas. With its cooling effect, it heals infections (especially in the throat and/or tonsils), lowers blood pressure and soothes burns. It is an excellent stone for women, treating PMS and menstrual cramps.
