Fire quartz (also called hematoid quartz when containing abundant iron oxide or hematite inclusions) is a variety of quartz (silicon dioxide) distinguished by warm red, orange, or rust-colored tones produced by microscopic inclusions or coatings of iron oxides, hematite, or limonite within or on the crystal. It occurs as crystalline points, clusters, or tumbled stones and forms in hydrothermal veins, pegmatites, or as secondary coatings in geodes and cavities. Notable sources include Brazil, Morocco, India, and parts of Africa and the United States. Extraction is typically by open-pit or subsurface mining of quartz-bearing veins and pockets or by collecting alluvial/cavity material; rough pieces are cleaned, cut, and polished for use in jewelry, cabochons, beads, and decorative specimens.

In metaphysical traditions, fire quartz is associated with grounding combined with energizing attributes—said to boost vitality, courage, motivation, and personal power while helping to transmute negative energy into constructive action. It’s used in practices aimed at increasing focus, willpower, and emotional resilience, and sometimes for chakra work (particularly root and sacral). These uses are traditional and anecdotal and are not a substitute for professional medical or psychological advice.
