I like this specimen; that means that it is kind of weird, usually, and this instance is no exception! It is basically made up of hundreds of intergrown botryoidal globules of Psilomelane. The material has a gray-black color and a matte luster, and is fairly heavy for its porosity. Amidst the globules are patches of crusted quartz, both crystalline and microcrystalline, that show signs of weathering. I really like psilomelane because of its wildly varied range of forms.
