The giant quartz crystal from Mozambique

We don’t know when and why this giant quartz crystal arrived at the old Geological Commission. It is an hyaline quartz variety with tourmaline crystals inside, looking as black needles, from the known Alto Ligonha (Mozambique) mines.

Its almost perfect crystallographic form is a rhombohedron of the Hexagonal System.
