Orange chalcedony / jasper fragments

Microcrystalline quartz (SiO₂), likely iron-stained chalcedony or jasper

AI-generated identification · may be incorrect

Typically hardness 6.5–7, opaque to slightly translucent, orange, cream, and tan with a dull to waxy luster; quartz has no cleavage and a conchoidal fracture. The rough, earthy texture suggests jasper or iron-oxide-stained chalcedony rather than a crystalline feldspar specimen.

Physical properties

Formation & geological history

Forms when silica-rich groundwater fills cavities or fractures, with iron oxides producing the orange coloration; commonly Cenozoic to older, depending on its host rocks. Exact identification and age require locality and testing.

Uses & applications

Used for cabochons, beads, carvings, tumbled stones, and ornamental objects; jasper is also collected as a lapidary material. These small rough fragments have little industrial value.

Geological facts

Orange color commonly comes from hematite or goethite inclusions. A streak, hardness, translucency, and acid test can help distinguish it from calcite or sandstone.

Field identification & locations

Common in volcanic terrains, sedimentary gravels, and weathered silica veins worldwide. It should scratch glass, resist dilute hydrochloric acid, and show a white streak; exact species cannot be confirmed from the image alone.
