Rose Quartz
Quartz var. Rose Quartz (IMA: Quartz) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal; typically occurs in massive form, rarely forming well-defined crystal faces. In massive form, it lacks a specific habit besides being anhedral.
Mineral Group
Silicates (Tectosilicate subgroup; Quartz group)
Chemical Formula
SiO2 (Silicon Dioxide) with trace amounts of titanium, iron, or manganese, and microscopic inclusions of fibrous dumortierite
Formation Process
Igneous (Pegmatitic). It crystallizes at high temperatures from silica-rich fluids and vapors during the final stages of magma cooling.
About This Crystal
A pale to rosy-pink variety of quartz. It is usually translucent to cloudy due to microscopic mineral inclusions. It exhibits a vitreous (glassy) luster and conchoidal fractures, appearing as a smooth, polished teardrop in this specimen.
Physical Characteristics
Color: Pink to rose red. Streak: White. Cleavage: Indistinct/None. Fracture: Conchoidal. Specific Gravity: 2.65. Tenacity: Brittle. Fluorescence: Occasionally weak purple under LWUV. Piezoelectric properties present.
Optical Properties
Refractive Index: 1.544–1.553. Birefringence: 0.009. Optical Character: Uniaxial positive. Some specimens exhibit asterism (star effect) due to oriented rutile inclusions.
Hardness & Durability
Origin Region
Brazil (Minas Gerais), Madagascar, South Africa, India, and the United States (South Dakota). Found primarily in late-stage hydrothermal veins and granite pegmatites.
Hardness & Durability
Mohs Hardness: 7. Toughness: Good. Highly durable for jewelry, though massive forms can have internal fractures that weaken the stone if struck.
Care & Maintenance
Clean with warm soapy water. Safe for ultrasonic cleaners unless heavily fractured. Avoid prolonged exposure to direct sunlight as colors may fade. Store separately from harder gems like Topaz or Sapphire.
Rarity & Value
Common. Generally affordable. Value is determined by color intensity (deeper pink is better), clarity, and size. High-quality transparent rose quartz is rarer and more valuable than the common milky variety.
Special Characteristics
Can exhibit a six-rayed star (asterism) when cut into cabochons. Often contains 'silk' or internal cloudy veining. Known for its distinct lack of external crystal faces compared to other quartz varieties.
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 foster emotional healing, peace, and compassion.
