Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal; typically occurs in massive form, rarely as individual crystals
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2 (Trace elements of Titanium, Iron, or Manganese cause the pink hue)
Formation Process
Igneous/Hydrothermal; typically forms in late-stage magmatic crystallization within pegmatites
About This Crystal
A translucent to nearly opaque variety of quartz with a pale pink to rose-red hue. It features a vitreous luster and a cloudy or milky appearance due to microscopic inclusion of fibrous dumortierite or similar minerals.
Physical Characteristics
Color: Pale to deep pink; Streak: White; Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Usually inert but can show weak purple under LWUV; Tenacity: Brittle.
Optical Properties
Refractive Index: 1.544–1.553; Birefringence: 0.009; Doubly Refractive; can exhibit asterism (star effect) if rutilated and cut en cabochon.
Hardness & Durability
Origin Region
Brazil (Minas Gerais), Madagascar, South Africa, India, and USA (South Dakota)
Hardness & Durability
Mohs Hardness: 7; Toughness: Good; Stability: Stable though color can fade if exposed to prolonged intense sunlight.
Care & Maintenance
Clean with warm soapy water; safe for ultrasonic cleaners in stable specimens. Store away from direct sunlight and harder gemstones like topaz or sapphire to prevent scratching.
Rarity & Value
Common; value is determined by color intensity and transparency. Deeper pinks and clearer specimens are more valuable. Treatments like irradiation are rare but possible.
Special Characteristics
Tyndall scattering often gives it a milky look; common 'internal fractures' or veining create a unique texture in polished spheres.
Lore & History
Historically used in ancient Egyptian and Roman civilizations as a stone of beauty and love. Modernly associated with the Heart Chakra and believed to promote emotional healing and unconditional love.
