Physical properties
Hardness: 7 Mohs, Color: Transparent/White/Brownish, Luster: Vitreous (glassy), Crystal Structure: Trigonal/Hexagonal, Cleavage: None/Conchoidal fracture
Formation & geological history
Forms in wide range of geological environments, including igneous intrusions, metamorphic rocks, and hydrothermal veins. It is one of the most abundant minerals in the Earth's crust.
Uses & applications
Used in glass manufacturing, electronics (due to piezoelectric properties), construction as an aggregate, and as a gemstone in jewelry.
Geological facts
Quartz is more resistant to weathering than most other minerals, which is why it is the primary component of most beach sands. It can occur in massive forms or as well-defined crystals.
Field identification & locations
Identify by its hardness (it will scratch glass) and lack of cleavage. This specific specimen is a very small, crushed fragment likely showing conchoidal fracture patterns.
