CALCITE: Calcite is a good stone for meditation. It is said to be helpful for the treatment of stress and anxiety, I.B.S., eczema and warts. It also improves memory and concentration. Calcite is thought to increase your intuition and encourages astral travel during meditation. Calcite encourages growth in small children and is also recommended for hyperactivity (A.D.H.D.). Red Calcite is a good choice for anaemia and for gout.
