This specimen is classified as a citrine because of its slightly yellow tint, but I could have calld it a smoky quartz, too, because at first glance the quartz looks gray. While most of the mass of the specimen is this cirtine, most of the surface is covered by an assortment of minerals, including albite, biotite, and very odd formations of a pink mineral that was documented as lepidolite, and while it does look like lepidolite in a few small areas, it mostly looks granular or even botryoidal, with an amethyst color. I do not know what it is, but it does lend color and contrast to the specimen.
