Rose Quartz
Quartz var. Rose Quartz (IMA-approved: Quartz) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal; typically occurs in massive, anhedral forms rather than well-defined crystals. In this specimen, it has been shaped into a polished sphere (orbicular habit).
Mineral Group
Silicates (Tectosilicate subgroup; Quartz group)
Chemical Formula
SiO2 (Silicon Dioxide) with trace impurities of Titanium, Iron, or Manganese (or microscopic inclusions of Dumortierite) causing the pink color.
Formation Process
Igneous/Pegmatitic formation; crystallizes from cooling magma in silica-rich pegmatites or hydrothermal veins at relatively high temperatures.
About This Crystal
A polished sphere displaying a soft, pale pink to rosy hue. The specimen is translucent with a vitreous to slightly waxy luster once polished. Inner internal fractures and 'cloudy' cloudy veining patterns are visible, giving it a depth of character.
Physical Characteristics
Color: Pale pink; Streak: White; Cleavage: None (poor); Fracture: Conchoidal; Specific Gravity: 2.65; Tenacity: Brittle; Fluorescence: Generally inert to weak purple under UV.
Optical Properties
Refractive Index: 1.544–1.553; Double Refraction (Birefringence): +0.009; No pleochroism. Some specimens show asterism (six-rayed star) if rutile inclusions are present, but not clearly visible here.
Hardness & Durability
Origin Region
Major sources include Brazil (Minas Gerais), Madagascar, South Africa, and the United States (South Dakota). Found primarily in granitic pegmatites.
Hardness & Durability
Mohs Hardness: 7; Toughness: Fair to Good; very stable for jewelry and decor. It is harder than steel but can chip if dropped due to its brittle nature.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid steam cleaners and ultrasonics if there are large internal fractures. Highly susceptible to fading if left in direct, prolonged sunlight.
Rarity & Value
Common; value is determined by color intensity (deeper pink is better), clarity, and size. Generally affordable; treatment like irradiation is rare but sometimes used to deepen color.
Special Characteristics
Displays translucency and characteristic internal 'frosty' inclusions. If containing aligned rutile needles, it may exhibit a six-rayed star under a single light source.
Lore & History
Historically used in Mesopotamian beads (c. 7000 BC) and Egyptian cosmetics. Symbolically known as the 'Stone of Unconditional Love,' traditionally associated with the Heart Chakra and emotional healing.
