Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone
Crystal System
Trigonal; typically occurs in massive form, though rare individual crystals (Pink Quartz) can be found in the hexagonal system
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2 (Silicon Dioxide) with trace inclusions of fibrous dumortierite, manganese, or titanium
Formation Process
Igneous; crystallizes from cooling magma in silica-rich pegmatites under hydrothermal conditions
About This Crystal
Translucent to semi-opaque pink stone with a vitreous to waxy luster. The specimen shown is a tumbled pebble, smooth with internal fractures and cloudiness characteristic of quartz
Physical Characteristics
Color: Pale to deep pink; Streak: White; Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Weak purple under UV
Optical Properties
Refractive Index: 1.544-1.553; Birefringence: 0.009; No pleochroism; can rarely exhibit asterism (star effect) due to rutile needle inclusions
Hardness & Durability
Origin Region
Madagascar, Brazil (Minas Gerais), South Africa, and the United States (South Dakota); forms primarily in pegmatites
Hardness & Durability
Mohs Hardness: 7; Toughness: Brittle; Stable in most conditions but can fade with prolonged heat or light exposure
Care & Maintenance
Clean with warm soapy water; avoid ultrasonic cleaners if heavily fractured; store away from direct sunlight to prevent color fading
Rarity & Value
Common; value is determined by color intensity and transparency. Deeper pinks are more valuable. Generally affordable ($1-$10 for tumbled stones)
Special Characteristics
Characterized by internal 'milky' or cloudy veining and microscopic fibers of dumortierite that produce the pink hue
Lore & History
Historically used in Roman and Egyptian jewelry. Traditionally known as the 'Stone of Unconditional Love,' associated with the Heart Chakra in modern crystal healing lore
