Kunzite is the pale pink to violet form of the mineral spodumene. In the case of Kunzite it is the presence of manganese mineral traces as the crystals form that cause the delightful pink and violet hues. As you turn a Kunzite gemstone in your hand it can flash from pink to violet or dark pink to colorless in some examples. This unusual phenomenon is called pleochroism and only occurs in a small number of gemstones. Kunzite can be found in different locations in the world, such as the USA, Madagascar, Brazil, and Afghanistan. Kunzite is one of the natural birthstones of those born in mid-autumn October 22 – November 20.
