Iron (Fe) can also cause a blue coloration in tourmaline, such as the variety commonly termed indicolite (Faye et al., 1968; Mattson and Rossman, 1987). However, the bright blue color characteristic of Paraíba tourmaline is caused by Cu (Rossman et al., 1991) and easily surpasses the intensity and hue of indicolite's Fe-related blues.
