Raw pink chalcedony (likely pink agate/jasper)

Microcrystalline quartz, SiO₂ (chalcedony); impurities may include iron oxides and other silicates

AI-generated identification · may be incorrect

Translucent salmon-pink to reddish material with waxy-to-glassy luster and irregular fracture; quartz hardness is about 6.5–7 Mohs, with no cleavage and specific gravity near 2.6. The dark brown/gray areas may be matrix or iron/manganese staining.

Physical properties

Formation & geological history

Forms when silica-rich groundwater fills cavities, fractures, or volcanic vesicles and precipitates as microcrystalline quartz, commonly in Cenozoic to older volcanic rocks. The specimen appears raw and mounted as jewelry.

Uses & applications

Used for cabochons, beads, carvings, ornamental stone, and collectors’ specimens; durable pieces are suitable for jewelry but should avoid sharp impacts and harsh chemicals.

Geological facts

Pink chalcedony overlaps visually with pink agate and jasper; translucent areas favor chalcedony, while opaque, heavily impure areas are often marketed as jasper. Color commonly results from iron-bearing inclusions or microscopic mineral impurities.

Field identification & locations

Look for translucency at thin edges, a waxy surface, conchoidal fracture, and absence of cleavage; it should not scratch easily with a steel knife. Common sources include Brazil, Madagascar, India, Turkey, and the western United States.
