Physical properties
Pale yellow-green, translucent, glassy luster, with irregular fracture; quartz is Mohs hardness 7 and has a trigonal crystal structure, with no cleavage. The image is not detailed enough to confirm the identification or distinguish it from other pale minerals.
Formation & geological history
Quartz forms in igneous and metamorphic rocks and in hydrothermal veins as silica-rich fluids cool; it occurs across geological ages.
Uses & applications
Quartz is used in glass, electronics, abrasives, and jewelry; attractive pieces may be collected or cut as gems.
Geological facts
Quartz is one of Earth’s most abundant minerals and commonly forms six-sided crystals, though this specimen’s shape is unclear.
Field identification & locations
Check for hardness (scratches glass) and absence of cleavage; common sources include Brazil, Madagascar, and many quartz-bearing regions worldwide. A photo alone cannot establish locality or precise variety.
