Pink Tourmaline has a Trigonal crystal system and is the mineral class of ring silicate with added oxide. It can be formed magmatically where it grows freely as large and many colored crystals, or, when its surrounding rock has been influenced by gases in the magma that contain boron, it is found very firmly embedded. The pink forms of Tourmaline are also known as Rubilite.
The Tourmaline family consists of seven color varieties which have a very stable basic structure. Its coloring is dependent upon the metals present as it grew. While found world wide, some of the nicest shades of this pink variety seem to come from certain areas of India and Brazil.
