A multicolored Tourmaline cabochon slice with rings of red, yellow and brown trigonal crystal patterns. Bicolor Tourmaline is a unique phenomena in the gem kingdom. Just like most Tourmaline species, it was formed in molten magma veins that penetrated the surrounding bedrock. Rich in a solution of water and minerals such as iron, lithium and manganese, over time Tourmaline crystals and other stones grew in their conducive environment. As bicolor Tourmaline crystals formed, they utilized the minerals that were most readily available. As concentrations of available minerals changed, it caused a shift in the predominant color in the crystal lattice.
