Fire Quartz
Quartz var. Hematoid Quartz · Semi-Precious Gemstone
Crystal System
Trigonal, massive to microcrystalline aggregate formed into tumbled beads
Mineral Group
Silicates (Tectosilicates)
Chemical Formula
SiO2 with Fe2O3 inclusions
Formation Process
Hydrothermal and magmatic processes where silica-rich solutions crystallize around pre-existing iron oxide or hematite minerals, trapping the red and orange inclusions inside the growing quartz host
About This Crystal
The specimen is a beaded stretch bracelet featuring polished, spherical beads of transparent to translucent quartz containing prominent red, orange, and brownish-red hematite and lepidocrocite inclusions, displaying a vitreous luster
Physical Characteristics
Color ranges from clear and milky white to deep reddish-brown; white streak; no cleavage; conchoidal fracture; specific gravity around 2.65; brittle tenacity; displays no significant magnetism but possesses piezoelectric properties
Optical Properties
Singly refractive or uniaxial positive with low birefringence (0.009); displays no significant pleochroism in the host quartz, but the inclusions create striking internal visual patterns
Hardness & Durability
Origin Region
Madagascar, Brazil, South Africa, and the USA; forms in hydrothermal veins and pegmatites
Hardness & Durability
Mohs hardness of 7; good durability and toughness, making it excellent for daily wear in jewelry like bracelets and pendants
Care & Maintenance
Clean with warm, soapy water and a soft cloth; avoid harsh chemicals, ultrasonic cleaners, and prolonged direct sunlight to prevent any surface alterations
Rarity & Value
Common to uncommon; value is determined by the clarity of the quartz host and the density, pattern, and vividness of the red and orange inclusions
Special Characteristics
Features distinct hematite and iron oxide inclusions suspended within the clear quartz matrix, creating a fiery or glittering internal landscape often referred to as fire quartz or harlequin quartz
Lore & History
Often associated in modern metaphysical practices with grounding energy, vitality, focus, and transforming negative energies into positive universal light, though these are traditional beliefs rather than scientific claims
