Tumbled quartz-rich pebble, possibly rose quartz or quartzite

Quartz (SiO₂), potentially quartzite if composed of fused quartz grains

AI-generated identification · may be incorrect

Small rounded, matte-to-waxy specimen with pale pink, cream, and gray coloration; likely Mohs hardness 7, vitreous when freshly broken, with no obvious cleavage and conchoidal fracture. The image is insufficient to confirm crystal structure or specific gravity.

AI Estimated Value

Approximately $1–$10 for a common tumbled pebble; potentially $10–$30 if unusually attractive, translucent, or confirmed as quality rose quartz.

Physical properties

Formation & geological history

Quartz forms in igneous, metamorphic, and hydrothermal settings; quartzite forms when sandstone is metamorphosed. Its rounded shape indicates stream abrasion or human tumbling; age cannot be determined from the image.

Uses & applications

Used for lapidary items, carvings, jewelry, countertops, glass, and industrial silica. As a small common pebble, it has modest collector value.

Geological facts

Pink color may result from trace iron, inclusions, or radiation-related defects, but appearance alone cannot distinguish rose quartz from pale quartzite.

Field identification & locations

Common in quartz-bearing gravels and metamorphic terrains worldwide. Test with a steel file or glass: true quartz should scratch glass and resist a steel knife; inspect a fresh surface for granular quartzite texture.
