Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically occurs in massive form (crystallocrystalline). Rare well-formed crystals are found in the related "Pink Quartz" variety, but common Rose Quartz lacks distinct crystal faces and forms large, anhedral masses.
Mineral Group
Silicates (Tectosilicate)
Chemical Formula
SiO2 with trace amounts of Titanium, Manganese, or Iron; coloration potentially caused by microscopic inclusions of fibrous Dumortierite-like minerals.
Formation Process
Igneous formation; crystallizes at high temperatures within cooling granite pegmatites and hydrothermal veins. The color is stable but results from the slow cooling and incorporation of trace elements.
About This Crystal
Massive, translucent to nearly opaque pale pink specimen. Exhibits a vitreous to greasy luster with irregular, rough surface features. The color is a soft, uniform pastel pink throughout the body of the stone.
Physical Characteristics
Color: Pale pink; Streak: White; Cleavage: None (poorly developed); Fracture: Conchoidal to uneven; Specific Gravity: 2.65; Tenacity: Brittle; Fluorescence: Weakly inert to faint purple under UV light.
Optical Properties
Refractive Index: 1.544-1.553; Birefringence: 0.009 (uniaxial positive); Pleochroism: Weak; notable for potential Diasterism (star effect) when cut into cabochons due to internal rutile needles.
Hardness & Durability
Origin Region
Madagascar, Brazil (Minas Gerais), South Africa, USA (South Dakota). Found primarily in granite pegmatites.
Hardness & Durability
Mohs hardness: 7. Excellent durability for jewelry; no cleavage makes it resistant to chipping, though it is brittle and can crack under sharp impact.
Care & Maintenance
Avoid prolonged exposure to direct sunlight as colors may fade. Clean with warm soapy water and a soft brush. Ultrasonic cleaners are generally safe but should be used with caution if the stone has surface-reaching fractures.
Rarity & Value
Very Common; inexpensive in massive form. Value increases significantly for depth of color, transparency, and 'star' phenomena (asterism). Often sold by weight or as tumbled stones.
Special Characteristics
Tyndall scattering and microscopic fibrous inclusions contribute to its cloudy appearance. Occasionally exhibits asterism (a six-rayed star) when polished.
Lore & History
Historically used in Talismans as early as 800-600 B.C. by Assyrians and Romans. Symbolically known as the 'Stone of Unconditional Love' and associated with the Heart Chakra in modern crystal healing traditions.
