Mined in 1989, this bright and deeply colored purple-blue fluorite is from the famous collection of Ross Lillie, broken up and sold nearly a decade ago now. You can see his notes, that he thought highly of the deep zoning here. Better in person, as the color is a little dark and the eye picks up the subtleties of the color phantom zones better than the camera does. As a final note, this is just very sparkly!
