Physical properties

Formation & geological history

Forms at relatively low temperatures in sedimentary and volcanic environments. It typically precipitates from silica-rich groundwater into cavities in rocks (geodes or veins) during late-stage hydrothermal activity.

Uses & applications

Used primarily in lapidary arts for cabochons, beads, and carvings. Often used in decorative jewelry and as a meditation stone in metaphysical circles.

Geological facts

Pink chalcedony is often associated with emotional healing and is a relatively rare color variant compared to blue or gray chalcedony. It is a microcrystalline form of quartz.

Field identification & locations

Identify by its waxy luster, conchoidal fracture, and lack of visible crystals. Commonly found in Brazil, Namibia, Turkey, and the USA (California and Oregon). Collectors look for uniform color and high translucency.
