Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically occurs in massive form without external crystal faces
Mineral Group
Silicates (Tectosilicate)
Chemical Formula
SiO2 with trace amounts of Titanium, Iron, or Manganese (or inclusions of Dumortierite)
Formation Process
Igneous/Magmatic; typically forms during the late-stage crystallization of granitic pegmatites
About This Crystal
A pale to medium pink specimen with a massive habit, vitreous to greasy luster, and translucent to cloudy transparency. It exhibits characteristic conchoidal fracture and internal veiling.
Physical Characteristics
Color: Pink; Streak: White; Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Usually inert but can show weak purple under LWUV; Piezoelectric.
Optical Properties
Uniaxial positive; Refractive Index: 1.544–1.553; Birefringence: 0.009; may show weak pleochroism and occasionally asterism (star effect) when polished.
Hardness & Durability
Origin Region
Brazil (Minas Gerais), Madagascar, South Africa, and the United States (South Dakota)
Hardness & Durability
Mohs Hardness: 7; Toughness: Fair to Good; Stability: Color may fade with prolonged exposure to sunlight or high heat.
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid ultrasonic cleaners if heavily fractured; store away from direct sunlight and harder gemstones like topaz or sapphire.
Rarity & Value
Common; value depends on color saturation, transparency, and size. Generally inexpensive; treatments are rare though dyeing is occasionally seen.
Special Characteristics
Massive rose quartz rarely forms crystals; pink color is often attributed to microscopic fibrous inclusions of a mineral similar to dumortierite.
Lore & History
Historically used in Mesopotamian jewelry (c. 7000 BC); traditionally known as the 'Stone of Unconditional Love,' associated with the Heart Chakra and emotional healing.
