Rose Quartz
Quartz var. Rose Quartz (silicon dioxide) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal; typically occurs in massive crystalline forms and rarely shows crystal faces; this specific specimen is carved into a five-pointed star habit.
Mineral Group
Silicates; Tectosilicate subgroup (Quartz family)
Chemical Formula
SiO2 (with trace amounts of Titanium, Iron, or Manganese occurring as microscopic dumortierite inclusions)
Formation Process
Igneous/Magmatic; forms from the crystallization of silica-rich magma in pegmatites or via hydrothermal precipitation in veins at moderate to high temperatures.
About This Crystal
Pale pink to rose-red hue, translucent to nearly opaque. This specimen shows a waxy to vitreous luster and a soft, milky appearance due to internal microscopic fibers. It has been carved into a polished star shape.
Physical Characteristics
Color: Pink; Streak: White; Cleavage: None/Indistinct; Fracture: Conchoidal; Specific Gravity: 2.65; Tenacity: Brittle; Fluorescence: Weak purple under UV light.
Optical Properties
Refractive Index: 1.544-1.553; Birefringence: 0.009 (Uniaxial positive); exhibits a milky translucency; may show asterism (star effect) if oriented and polished correctly as a cabochon.
Hardness & Durability
Origin Region
Major sources include Brazil, Madagascar, South Africa, and the United States (South Dakota); typically found in granite pegmatites and hydrothermal veins.
Hardness & Durability
Mohs Hardness: 7; Good toughness due to lack of cleavage; highly durable for jewelry and decorative use; resistant to most household chemicals.
Care & Maintenance
Clean with warm soapy water; safe for ultrasonic cleaners generally. Store away from prolonged direct sunlight as intense UV exposure can cause the pink color to fade over time.
Rarity & Value
Common; widely available and affordable. Value is determined by color intensity (deeper pink is preferred) and transparency. Carved pieces like this star are valued for craftsmanship.
Special Characteristics
Displays TYndall scattering which gives it the characteristic 'milky' look; can occasionally contain rutile or dumortierite inclusions that cause a six-rayed star effect (asterism).
Lore & History
Historically used in ancient Egyptian and Roman civilizations for talismans. In traditional lore, it is known as the 'Stone of Unconditional Love,' associated with the Heart Chakra and emotional healing.
