Physical properties
Small, pale tan to translucent fragment with a glassy-to-dull luster; quartz has hardness 7, a hexagonal crystal structure, no cleavage, and conchoidal fracture. The image is not detailed enough to confirm its identity or measure properties.
Formation & geological history
Quartz commonly forms in igneous and metamorphic rocks and in hydrothermal veins, then survives weathering and becomes rounded or chipped sediment. Its geological age cannot be determined from the photograph.
Uses & applications
Quartz is widely used in glass, electronics, abrasives, and construction; attractive pieces may be used in jewelry or collections.
Geological facts
Quartz is one of Earth’s most abundant minerals and occurs in many colors and forms.
Field identification & locations
A likely quartz fragment is suggested by its pale, somewhat translucent appearance, but a closer view and hardness or streak tests would help distinguish it from other minerals. Quartz is common worldwide.
