Pink chalcedony or weathered pink quartzite
Microcrystalline quartz (SiO₂), possibly iron-bearing chalcedony
AI-generated identification · may be incorrectPale pink, opaque to weakly translucent, with a dull-to-waxy luster and fine-grained texture; quartz hardness is about 7 Mohs, no obvious cleavage, and specific gravity near 2.6. The rounded edges suggest natural weathering or tumbling.

Physical properties
Pale pink, opaque to weakly translucent, with a dull-to-waxy luster and fine-grained texture; quartz hardness is about 7 Mohs, no obvious cleavage, and specific gravity near 2.6. The rounded edges suggest natural weathering or tumbling.
Formation & geological history
Likely formed from silica-rich fluids depositing microcrystalline quartz, with iron or other trace impurities producing the pink color; alternatively it may be a quartzite fragment. Exact age and locality cannot be determined from the photograph.
Uses & applications
Used as a decorative stone, lapidary rough, beads, cabochons, and tumbled specimens; low-grade pieces have little industrial value.
Geological facts
Pink chalcedony can resemble rose quartz, jasper, or dyed stone. Chalcedony is typically waxier and more uniformly translucent or opaque than crystalline rose quartz.
Field identification & locations
Commonly found in volcanic cavities, silica-rich veins, and weathered gravels worldwide. A steel file should not easily scratch genuine quartz, though testing should be done inconspicuously; an acid test is not useful.
