Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal crystal system. Typically occurs in massive forms; well-defined crystals are extremely rare and are often referred to as Pink Quartz or Crystalline Rose Quartz.
Mineral Group
Silicates (Tectosilicate subgroup; Quartz group)
Chemical Formula
SiO2 (Silicon Dioxide with trace inclusions of Manganese, Titanium, or Iron; pink hue also attribute to microscopic fibers of a borosilicate mineral similar to dumortierite)
Formation Process
Igneous/Magmatic. Forms during the late-stage crystallization of pegmatites, where fluids rich in silica and trace metallic elements cool slowly at high temperatures and pressures.
About This Crystal
A translucent to nearly opaque sphere exhibiting a pale pink to rose-red body color. The surface shows a vitreous to waxy luster with visible internal fractures and cloudy, milky inclusions that give the stone a characteristic hazy appearance.
Physical Characteristics
Color: Pale pink to rose; Streak: White; Cleavage: None (indistinct); Fracture: Conchoidal; Specific Gravity: 2.65; Tenacity: Brittle; Fluorescence: Generally inert to weak purple under UV light; Piezoelectric properties present.
Optical Properties
Refractive Index: 1.544-1.553; Birefringence: 0.009; Doubly refractive (uniaxial positive); Pleochroism: Weak; May exhibit asterism (star effect) if oriented and polished correctly due to rutile inclusions.
Hardness & Durability
Origin Region
Madagascar, Brazil (Minas Gerais), South Africa, and the United States (South Dakota). Found primarily in granitic pegmatites and hydrothermal veins.
Hardness & Durability
Mohs Hardness: 7; Toughness: Good (no cleavage); Stable under normal light but may fade with prolonged exposure to high heat; Excellent wearability for all jewelry types.
Care & Maintenance
Safe to clean with warm soapy water and a soft brush. Avoid ultrasonic and steam cleaners as internal fractures may expand. Store away from direct, prolonged sunlight to prevent color fading.
Rarity & Value
Common and abundant. Value is determined by color intensity (deep pink is more valuable), transparency, and presence of asterism. Mostly sold as beads, cabochons, and decorative spheres like the one pictured.
Special Characteristics
Shows internal veining and cloudiness. High-quality specimens can show 'Tyndall scattering' or a six-rayed star (asterism) when illuminated by a single point light source.
Lore & History
Historically used in ancient Egyptian and Roman civilizations for talismans and facial masks. Traditionally known as the 'Stone of Unconditional Love,' it is associated with the Heart Chakra and believed to promote emocional healing and peace.
