Physical properties
Hardness: 6.5-7 (Mohs); Color: Deep red to brownish-red; Luster: Vitreous to dull; Crystal structure: Trigonal (microcrystalline quartz); Cleavage: None, conchoidal fracture
Formation & geological history
Formed through the deposition of silica in hydrothermal veins or volcanic ash, combined with iron inclusions that provide the red hue. Typically sedimentary but can be associated with volcanic environments.
Uses & applications
Used primarily in jewelry (cabochons, beads), decorative objects, and is highly valued in metaphysical communities as a 'supreme nurturer'.
Geological facts
The vibrant red color is caused by the presence of iron oxide (hematite). It has been used for centuries in seals, amulets, and ring stones for its believed protective qualities.
Field identification & locations
Identify by its opaque quality and deep brick-red color. It is common in riverbeds and arid regions globally; massive deposits are found in India, Russia, Brazil, and the USA (Southwest).
