Physical properties

Formation & geological history

Likely weathered quartz from a silica-rich igneous or metamorphic rock, later rounded by transport or tumbling. Its exact geological age and locality cannot be determined from the photograph.

Uses & applications

Used as a decorative tumbled stone, craft material, or inexpensive collectible; quartz is also important in glass, ceramics, electronics, and abrasives. Typical value is about $1–$5 for a piece this size.

Geological facts

Pink coloration may result from trace inclusions or irradiation-related defects, but visual identification as true rose quartz is uncertain. The rounded surface appears human-tumbled or naturally waterworn.

Field identification & locations

Test with a steel file or knife: quartz should resist scratching; it should scratch glass but not be scratched by steel. Common sources include Brazil, Madagascar, India, and the United States; confirm identity with hardness and streak tests.
