Polished pink chalcedony (possibly carnelian)

Microcrystalline quartz, SiO₂; chalcedony variety, with exact variety uncertain from the image

AI-generated identification · may be incorrect

Small, tumbled, opaque-to-translucent salmon-pink stone with a smooth polish and waxy-to-vitreous luster. Quartz hardness is about 7 Mohs; trigonal crystal structure, but crystals are too fine-grained to see, and there is no prominent cleavage.

Physical properties

Formation & geological history

Silica-rich fluids deposited microscopic quartz in rock cavities or fractures, later colored by trace impurities; chalcedony can form in many geological ages and settings.

Uses & applications

Used for beads, pendants, cabochons, and ornamental objects; this small polished piece is primarily a craft or jewelry material.

Geological facts

Carnelian is typically orange-red, while pink chalcedony is often sold under broad trade names; color alone cannot confirm the variety.

Field identification & locations

Look for quartz-like hardness, a smooth waxy surface, and no cleavage; agate-like banding may occur but is not visible here. Chalcedony occurs worldwide, including Brazil, India, Madagascar, and the western United States.
