The datolites from Michigan's copper country generally weather out of the amygdaloidal basalts. Since they are closely associated with the copper deposits they are often invested with enough copper to give them a beautiful terra-cotta color, like this one. But in this consistent color and depth of hue, it is rare. A fine miniature!
