    Andalusite – Natural, Faceted, Green, 7.01 ct

    Depending on the viewing angle, andalusite can show green, red, or brown colors. Its pleochroism is so extreme, it can even show multiple colors at the same time. This vintage, 7.01-ct, modified shield-cut andalusite shows green, brown, and red colors in its facet reflections. Photo © Joel E. Arem, PhD, FGA. Used with permission.
