AI Estimated Value

Approximately $1–$10 as an ordinary small specimen; higher only if crystals, unusual inclusions, or proven locality are present.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich igneous and hydrothermal fluids and commonly fills veins in older crystalline rocks; its age depends on its host deposit. Weathering can release rounded quartz pebbles and cobbles.

Uses & applications

Common quartz is used in glass, ceramics, abrasives, engineered stone, and electronics; attractive pieces are used as décor or inexpensive mineral specimens. This small rough specimen likely has modest commercial value.

Geological facts

Quartz is one of Earth’s most abundant minerals and is chemically resistant, allowing it to survive erosion. Milky color results mainly from microscopic fluid inclusions and structural defects.

Field identification & locations

Look for glassy luster, lack of cleavage, conchoidal or irregular fracture, and resistance to scratching by steel; quartz should scratch ordinary glass. Common worldwide, especially in Brazil, the United States, Madagascar, and hydrothermal vein districts.
