  • Mineral Identification Key - Table IIIB-2

    Notes: The Tourmaline Group species can be difficult to tell apart without specific locality data. The overlap of color and habit can make crystals without matrix very difficult to distinguish without lab tests. Most of the Garnet Group species can be very difficult to tell apart. Color alone is rarely if ever diagnostic; and S.G.s overlap too much to make them useful alone or with color.
