Physical properties
Colorless to cloudy white with a vitreous luster; Mohs hardness 7, trigonal crystal system, and no cleavage, with conchoidal fracture. The small specimen appears translucent and naturally terminated, though the image does not show enough detail to confirm its exact variety.
Formation & geological history
Quartz crystallizes from silica-rich fluids or magma in many geological settings; its age depends on the host deposit and cannot be determined from the image.
Uses & applications
Commonly used for jewelry, ornaments, electronics, and industrial silica; small crystals are also collected as mineral specimens.
Geological facts
Quartz is one of Earth’s most abundant minerals and produces a piezoelectric response when mechanically stressed.
Field identification & locations
Look for glassy luster, hardness sufficient to scratch glass, and a six-sided prismatic form; quartz occurs worldwide in veins, pegmatites, and sedimentary rocks. The specimen’s locality and quality are unknown from the photo.
