Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically found in massive forms without distinct crystal faces. Rarely occurs as individual crystals.
Mineral Group
Silicates (Tectosilicate)
Chemical Formula
SiO2 with trace amounts of Titanium, Manganese, or Iron
Formation Process
Igneous/Hydrothermal: Forms during the cooling of silica-rich magma in pegmatites at high temperatures and pressures.
About This Crystal
The specimen is a polished sphere showcasing a soft pastel pink hue. It displays a translucent to cloudy transparency with a vitreous luster and characteristic internal fractures and veining.
Physical Characteristics
Color: Pale pink to rose red; Streak: White; Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Usually inert but may show weak purple.
Optical Properties
Refractive Index: 1.544–1.553; Birefringence: 0.009 (Uniaxial positive); Pleochroism: Weak; may exhibit asterism (star effect) if rutilated.
Hardness & Durability
Origin Region
Madagascar, Brazil (Minas Gerais), South Africa, and the United States (South Dakota). Found primarily in pegmatites.
Hardness & Durability
Mohs Hardness: 7; Toughness: Good (due to lack of cleavage); Stable for daily wear but sensitive to thermal shock.
Care & Maintenance
Clean with warm soapy water. Avoid ultrasonic cleaners or steam. Store away from direct sunlight to prevent fading of the pink color.
Rarity & Value
Common; Value is determined by color intensity, transparency, and size. Irradiated or dyed stones exist but are less valuable.
Special Characteristics
Can exhibit a six-rayed star (asterism) when cut into spheres or cabochons if microscopic rutile inclusions are present.
Lore & History
Historically used in talismans in Ancient Egypt and Rome. Traditionally known as the 'Stone of Unconditional Love,' associated with the Heart Chakra.
