This small specimen of autunite is actually quite nice - it shows the typical habit and characteristic shapes and colorings of autunite. The color, for the most part, it an intense lemon yellow, with one side showing hints of green, and a notch that is distinctly green. This lemon is not quite ripe! The very thin, square crystals are organized in a single thick book, and the face shows a concave form. The crystals are translucent and have a pearly luster.
