This display piece consists of at least 3 intergrown Muscovite "books" that are generally in very good condition. These books show reasonably good monoclinic bladed form and have the standard micaceous basal parting of all members of the mica group. Their color is extraordinary - each book consists of a "core" of material that has a pale pink or lavender coloration, off of which grew more material with the standard yellow-gray color of Muscovite. I do not know if the pink material is actually lepidolite. A small amount of quartz or quartzite is present on the piece, but it is almost entirely Muscovite by mass.
