4th, 5th, 6th and 7th chakras. Tanzanite is a lovely and powerful gem belonging to the Zoisite family of minerals. It is was discovered in Tanzania, Africa in 1967. Tanzanite is one of the most powerful and valuable of all healing stones. This gemstone stimulates the heart, throat, third eye and crown chakras.
