Possible milky quartz vein or nodule

Quartz (SiO₂), provisionally identified from the visible white translucent material

AI-generated identification · may be incorrect

White to translucent, vitreous-looking material embedded in a pale weathered host rock; hardness 7 on the Mohs scale, trigonal crystal structure, no cleavage, and conchoidal fracture. The image does not show enough detail to identify the host rock or confirm the mineral.

Physical properties

Formation & geological history

Quartz commonly fills fractures as hydrothermal fluids cool, or forms as a nodule; its age depends on the host geology and cannot be determined from the photograph.

Uses & applications

Quartz is widely used in glass, electronics, and construction, and attractive specimens are collected or fashioned into ornaments.

Geological facts

Quartz is one of Earth’s most abundant minerals and resists weathering, so it often remains visible in outcrops after softer minerals erode.

Field identification & locations

Look for a glassy luster, hardness sufficient to scratch glass, and absence of cleavage; a scratch or close-up inspection would help distinguish quartz from calcite. The specimen appears to be in place, so no reliable location or quality-based price can be given; common small quartz pieces typically sell for about $1–$20.
