Iron-stained quartz with possible feldspar

Quartz (SiO₂), possibly with feldspar and iron-oxide staining

AI-generated identification · may be incorrect

A rough, pale white-to-pink specimen with glassy to dull surfaces and rusty-red patches. Quartz has Mohs hardness 7, a trigonal crystal structure, no cleavage, and conchoidal fracture; the image does not show enough detail to confirm the associated minerals.

AI Estimated Value

About $1–$10 for a common rough specimen of this apparent size; higher value would require confirmed, well-formed crystals or unusual mineral associations.

Physical properties

Formation & geological history

Likely formed as quartz-rich material in a vein or pegmatite, with pink coloration from iron oxides or feldspar. Its age and exact formation setting cannot be determined from the photograph.

Uses & applications

Quartz is widely used in glass, electronics, and decorative stone; attractive pieces may be kept as inexpensive mineral specimens.

Geological facts

Iron oxides can stain otherwise colorless quartz pink, red, or brown, while feldspar commonly gives quartz-rich rocks a pink tone.

Field identification & locations

Look for hardness near 7 and lack of cleavage; a glass scratch test can help distinguish quartz from softer minerals. Quartz occurs worldwide in veins and many igneous and metamorphic rocks.
