Milky Quartz
Quartz var. Milky Quartz · Mineral Specimen
Crystal System
Trigonal, massive to xenomorphic habit with no well-developed external crystal faces visible in this specimen.
Mineral Group
Silicates (Tectosilicates)
Chemical Formula
SiO2
Formation Process
Hydrothermal and magmatic processes, precipitating from silica-rich aqueous solutions at various temperatures and pressures.
About This Crystal
An opaque to translucent, whitish to greyish crystalline rock fragment showing a vitreous to greasy luster with minor surface weathering and iron staining.
Physical Characteristics
White to light gray body color, white streak, conchoidal fracture, lack of cleavage, specific gravity around 2.65, brittle tenacity.
Optical Properties
Uniaxial positive optical character with weak birefringence of 0.009, generally optically inactive for complex phenomena due to high inclusion density.
Hardness & Durability
Origin Region
Worldwide distribution; commonly found in pegmatites, hydrothermal veins, and metamorphic rocks globally.
Hardness & Durability
Mohs hardness of 7, good durability, resistant to scratching by most common materials except topaz, corundum, and diamond.
Care & Maintenance
Wash with warm soapy water and a soft brush; avoid harsh acids (except hydrofluoric acid) and store away from softer stones.
Rarity & Value
Extremely common mineral, of low monetary value unless part of a unique mineral assemblage or large crystal cluster.
Special Characteristics
Contains microscopic fluid and gas inclusions that give it the characteristic milky, cloudy appearance.
Lore & History
Historically used across many cultures for arrowheads, tools, and decorative objects. In metaphysical lore, it is often associated with clarity, amplification of energy, and the Crown Chakra, though these are traditional beliefs rather than scientific facts.
