QUARTZ SMOKEY (MORION) (LARGE CABINET)

Quartz is a robust crystalline mineral made up of silica, or silicon dioxide. Its structure consists of a continuous arrangement of SiO4 silicon-oxygen tetrahedra, where each oxygen atom is shared between two tetrahedra, resulting in the chemical formula SiO2. This classification places quartz as a framework silicate mineral in terms of structure and as an oxide mineral in terms of composition. It ranks as the second most prevalent mineral in the continental crust of Earth, following feldspar.

The dark black color of this quartz is caused by natural radiation and is a rare find. This specimen is about 50 years old and not fully cleaned.

The market is flooded with "radiated" smokey quartz, which means that the natural circumstances have been imitated to generate the darker smokey crystals.
