Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically occurs in massive, anhedral forms; rarely forms distinct crystals
Mineral Group
Silicates (Tectosilicate subgroup; Quartz group)
Chemical Formula
SiO2 (Silicon Dioxide) with trace amounts of Titanium, Iron, or Manganese
Formation Process
Igneous (crystallization within late-stage granite pegmatites or hydrothermal veins at moderate temperatures)
About This Crystal
Pale pink to rose-red hue, translucent to nearly opaque with a greasy to vitreous luster. This specimen shows a typical massive, fractured appearance with internal cloudiness and lack of crystal faces.
Physical Characteristics
Pink color; white streak; no cleavage; conchoidal fracture; specific gravity 2.65; brittle; non-fluorescent (usually); piezoelectric properties.
Optical Properties
Refractive index 1.544-1.553; uniaxial positive; weak pleochroism; may show asterism (star effect) if oriented and polished.
Hardness & Durability
Origin Region
Brazil (Minas Gerais), Madagascar, South Dakota (USA), India, Namibia, and South Africa
Hardness & Durability
Mohs hardness 7; high toughness due to lack of cleavage; stable for most jewelry, though can be sensitive to extreme thermal shock.
Care & Maintenance
Clean with warm soapy water; avoid ultrasonic cleaners if fractured; store away from prolonged direct sunlight to prevent color fading.
Rarity & Value
Common; value depends on color saturation and translucency. Large rough chunks are inexpensive; deep pink, translucent material is higher value. Usually untreated, though occasionally dyed.
Special Characteristics
May exhibit a 'star' effect (asterism) when cut into cabochons due to microscopic rutile inclusions; milky appearance caused by microscopic fluid or mineral inclusions.
Lore & History
Historically linked to ancient Egyptian and Roman civilizations as a stone of beauty; traditionally known as the 'Stone of Unconditional Love' in crystal healing, associated with the heart chakra.
