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.  Through integration, Tanzanite works to connect the mind and the heart, allowing one to be more centered so we can understand this important connection of understanding thoughts through the love in our hearts.  The wisdom of Tanzanite will help us to be more spiritual, allow us to feel true love, joy and pleasure.  It activates the throat chakra for clear communication of one's highest truth. It can also be used to enhance psychic abilities. These Tanzanite Gem pieces are quite rare and hard to come by.  I am honored to be able to offer you these incredible gemstones. Again, it is difficult to find this quality of rough Tanzanite. it is sublime!
