Physical properties

Formation & geological history

Formed in hydrothermal veins or igneous rocks during the late stages of magma cooling when silica-rich fluids permeate rock cavities; common in various geological ages ranging from Precambrian to Cenozoic.

Uses & applications

Primarily used as a decorative specimen for mineral collections, in crystal healing practices, or cut into cabochons and beads for jewelry.

Geological facts

The reddish spots or coating are caused by small amounts of iron oxide (hematite) leaching into the quartz crystals as they grow; it is often marketed under trade names like 'Fire Quartz' or 'Ferruginous Quartz'.

Field identification & locations

Identify by its 7 hardness (it will scratch glass) and characteristic internal reddish staining; often found in quartz-rich regions of Brazil, Madagascar, and the United States.
