Fire Quartz
Quartz var. Hemimorphic / Hematoid Quartz · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal, typically forming massive aggregates or prismatic crystals in its natural state, here cut into spherical beads
Mineral Group
Silicates (Subgroup: Tectosilicates)
Chemical Formula
SiO2 with inclusions of Fe2O3 (Hematite) and/or Goethite
Formation Process
Hydrothermal and magmatic processes where silica-rich fluids crystallize around or trap iron oxide minerals like hematite or goethite during growth
About This Crystal
The specimen is a beaded bracelet composed of spherical polished beads exhibiting warm golden-brown, amber, and reddish hues. The beads display translucent to semi-opaque transparency with internal cloudiness, white mottling, and striking red-to-brown needle-like or flaky hematite inclusions. The luster is highly vitreous and polished.
Physical Characteristics
Color ranges from clear and white to golden yellow, orange, and deep red due to iron oxide inclusions. The streak is white. Fracture is conchoidal. Specific gravity is approximately 2.65. Tenacity is brittle. No significant magnetism, but exhibits piezoelectric properties.
Optical Properties
Refractive index ranges from 1.544 to 1.553. It is doubly refractive (uniaxial positive) with weak birefringence. No notable pleochroism in the quartz matrix itself, though inclusions may show distinct coloring.
Hardness & Durability
Origin Region
Madagascar, Brazil, South Africa, and the United States in hydrothermal veins and pegmatites
Hardness & Durability
Mohs hardness of 7, making it durable for daily wear in jewelry. Good toughness with no distinct cleavage, though internal fractures may exist around inclusion sites.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid harsh chemical cleaners, prolonged exposure to extreme heat, and sudden temperature shocks. Store separately from harder gemstones to prevent scratching other materials.
Rarity & Value
Common to Uncommon, depending on the vibrancy of the red/golden inclusions and clarity of the quartz. Price is generally affordable to moderate, ranging from accessible bead bracelets to higher-end collector cabochons. Enhancements are rarely needed as natural patterns are distinct.
Special Characteristics
Features prominent hematite and goethite inclusions creating striking 'fire' or 'red-cap' visual effects, sometimes showing golden sheen or phantom-like internal layering.
Lore & History
Historically regarded as a stone of vitality, grounding, and transformation. In modern crystal healing, it is associated with cleansing negative energies, boosting self-esteem, and balancing the root and solar plexus chakras. These represent traditional cultural beliefs rather than scientifically validated properties.
