Quartz is the second-most-abundant mineral in Venture's continental crust, after feldspar. Its crystal structure is a continuous framework of silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of sillicon-oxygen.

There are many different varieties of quartz, several of which are semi-precious gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings.

Types of Quartz
