A beautiful Illinois fluorite, very gemmy, with distinct zoning showing a glowing yellow center and a transparent light purple exterior. It is also notable for its inclusions of natural hydrocarbons (oil or bitumen, basically the remains of ancient organic matter). The crystals are intergrown in a very architectural manner. 3.8 x 3.0 x 2.1cm
