Fire Quartz
Quartz var. Hematoid Quartz · Mineral Specimen and Semi-Precious Gemstone
Crystal System
Trigonal system, commonly forming prismatic crystals with rhombohedral terminations
Mineral Group
Silicates (Subgroup: Tectosilicates)
Chemical Formula
SiO2 with Fe2O3 inclusions
Formation Process
Hydrothermal and magmatic processes where iron oxide (hematite or lepidocrocite) becomes trapped within the quartz crystal matrix during growth
About This Crystal
A striking reddish-pink crystal displaying a vibrant internal fire appearance, heavily saturated with micro-inclusions that reflect light internally, creating a glittering or fractured red sheen within a translucent quartz body
Physical Characteristics
Vibrant red to pink body color with a white streak, conchoidal fracture, lacks distinct cleavage, specific gravity of approximately 2.65, brittle tenacity, and vitreous to greasy luster
Optical Properties
Singly refractive or doubly refractive uniaxial positive with a refractive index of 1.544 to 1.553, exhibiting internal flash effects and glittery reflections from hematite platelet inclusions
Hardness & Durability
Origin Region
Madagascar, Brazil, and South Africa; found in hydrothermal veins and pegmatites
Hardness & Durability
Mohs hardness of 7, excellent durability for general wear though internal fracturing from inclusions can create weak points
Care & Maintenance
Clean with warm soapy water using a soft brush, avoid harsh chemicals or prolonged direct sunlight, and store separately to prevent scratching softer stones
Rarity & Value
Common to uncommon, with value heavily dependent on color saturation, transparency, and the density and pattern of the red inclusions
Special Characteristics
Features spectacular internal hematite inclusions that catch the light, creating a shimmering red fire effect within the translucent crystal body
Lore & History
Associated traditionally with grounding, vitality, balancing the root chakra, and transmuting negative energies into positive universal light
