igneous
Tumbled pink granite or feldspar-rich pebble
Granite; chiefly quartz (SiO₂), feldspar, and minor mica, though the specimen may be pink orthoclase feldspar
AI-generated identification · may be incorrectSmall rounded, polished pebble with pale pink-beige color and dark specks; likely Mohs 6–7, vitreous to slightly dull luster, granular crystalline texture, no obvious cleavage visible, and specific gravity about 2.55–2.75.

Physical properties
Small rounded, polished pebble with pale pink-beige color and dark specks; likely Mohs 6–7, vitreous to slightly dull luster, granular crystalline texture, no obvious cleavage visible, and specific gravity about 2.55–2.75.
Formation & geological history
Likely weathered from granitic or feldspar-rich igneous rock formed by slow crystallization of magma deep in Earth’s crust, commonly Precambrian to younger; tumbling produced its smooth shape.
Uses & applications
Used as a decorative or craft stone, aquarium gravel, landscaping material, or inexpensive lapidary specimen; not typically jewelry-grade.
Geological facts
The dark flecks may be biotite mica or inclusions, while the pink color commonly comes from iron-bearing potassium feldspar. Exact identification is limited by the small, polished, low-resolution specimen.
Field identification & locations
Common in granite terrains and glacial or river gravels; a glassy quartz grain, visible feldspar cleavage, and a mixed-grain texture support granite. A uniform salmon color could instead indicate pink feldspar or dyed stone.
