White Quartz
Quartz var. Milky Quartz · Mineral Specimen / Decorative Stone
Crystal System
Trigonal, typically forming as water-worn pebbles or massive aggregates in this tumbled state
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2
Formation Process
Forms via hydrothermal veins, pegmatites, and igneous crystallization, subsequently weathered and water-tumbled in sedimentary environments
About This Crystal
Two smooth, water-worn tumbled stones of off-white to creamy translucent quartz, showing a milky, cloudy interior appearance with subtle internal fractures and uneven light transmission
Physical Characteristics
Color is milky white to off-white, white streak, conchoidal fracture with no true cleavage, specific gravity of approximately 2.65, vitreous to greasy luster when polished
Optical Properties
Uniaxial positive, refractive index of 1.544 to 1.553, low birefringence, generally non-pleochroic
Hardness & Durability
Origin Region
Found worldwide; common in alluvial deposits, riverbeds, and beaches globally
Hardness & Durability
Mohs hardness of 7, excellent durability with no cleavage planes, highly resistant to scratching, making it very suitable for general jewelry and handling
Care & Maintenance
Easy to maintain; can be cleaned safely with warm soapy water and a soft brush, resistant to most household chemicals and stable in sunlight
Rarity & Value
Extremely common worldwide, low commercial value, widely used for tumbled stones, lapidary projects, and decorative purposes
Special Characteristics
Displays a characteristic milky turbidity caused by microscopic liquid or gas-filled fluid inclusions trapped during crystal growth
Lore & History
Historically used across many ancient cultures for tools and talismans; in modern crystal healing, milky quartz is traditionally associated with emotional clarity, the crown chakra, and amplification of positive energy, though these remain traditional beliefs rather than scientific claims
