Alternate December Birthstone
Tanzanite is a dark-blue variety of the mineral zoisite, originally found only in Tanzania, Africa. Now also found in Pakistan, tanzanite is pleochroic, meaning it appears different colors – purple, gray or blue – depending on the angle from which it is viewed. At times it is heat-treated to remove brown areas and improve the color. Metaphysically, tanzanite is used to assist with communication and for calming the overactive psyche and balancing the mental with the emotional.
