    1. 1 Color in Minerals GLY 4200 Fall, 2011

    2. 2 Color Sources Minerals may be naturally colored for a variety of reasons - among these are: Selective absorption Crystal Field Transitions Charge Transfer (Molecular Orbital) Transitions Color Center Transitions Dispersion

    3. 3 Characteristic Color Color is characteristic for some minerals, in which case it is idiochromatic and thus may serve as an aid to identification Color is often quite variable, which is called allochromatic, and thus may contribute to misidentification

    4. 4 Visible Light Visible light, as perceived by the human eye, lies between approximately 400 to 700 nanometers
