Perimorphic growth of Quartz overlying a tetrahedral crystal, crystal which was probably Helvine, whose morphology, very neat, remains after the process of coating. The crystal is very aerial, standing on a group of smoky Quartz crystals, with a dodecahedral crystal of Fluorite and it is completely hollow. Though it appears so, the hole on a vertex of the crystal is not a break, but a shape of dissolution, as the detailed photo neatly shows.
