This is a small quartz geode containing a layer of pure white kaolinite coating the bottom half of the cavity. Under a loupe, the kaolinite looks much like snow on a landscape, and my 15x loupe does reveal individual crystals, but just barely. That makes these crystals rather huge by kaolinite standards, although I may be seeing books of even smaller crystals. The easily examined translucent crystals of this specimen are quartz, likely with kaolinite inclusions to lend a milky appearance.
