Rose Quartz
Quartz var. Rose (Silicon Dioxide) · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically occurs in massive crystalline aggregates. Well-formed individual crystals are extremely rare and differ mineralogically (often called pink quartz).
Mineral Group
Silicates; Tectosilicate (Framework Silicate) subgroup.
Chemical Formula
SiO2 with trace amounts of titanium, iron, or manganese; color can also be caused by microscopic inclusions of fibrous dumortierite.
Formation Process
Igneous/Pegmatitic formation; crystallizes from cooling magma in mineral-rich water at moderate to high temperatures within granitic pegmatites.
About This Crystal
A translucent to semi-transparent soft pink specimen with a vitreous to waxy luster. This specific piece shows a conchoidal fracture and an irregular, chunky massive habit typical of raw quartz shards. Internal veining and cloudy inclusions are visible.
Physical Characteristics
Color: Pale to rose pink; Streak: White; Cleavage: None; Fracture: Conchoidal (shell-like curves); Specific Gravity: 2.65; Tenacity: Brittle; Fluorescence: Occasionally weak purple under longwave UV.
Optical Properties
Refractive Index: 1.544-1.553; Birefringence: 0.009 (uniaxial positive); Pleochroism: Weak; may show asterism (star effect) if cut into cabochons due to rutile inclusions.
Hardness & Durability
Origin Region
Madagascar, Brazil (Minas Gerais), South Africa, and the United States (South Dakota). Found primarily in pegmatites.
Hardness & Durability
Mohs hardness: 7. Excellent durability for jewelry; no cleavage makes it resistant to splitting, though it can chip due to its brittle nature.
Care & Maintenance
Wash with warm soapy water. Avoid prolonged exposure to direct sunlight as UV radiation can cause the pink color to fade over time. Do not expose to harsh acids.
Rarity & Value
Common and abundant. Value is determined by color intensity (deeper pink is better), transparency, and size. Generally inexpensive but high-quality Madagascar material commands a premium.
Special Characteristics
Exhibits a characteristic cloudy appearance due to microscopic fibrous inclusions. Rare specimens can exhibit a six-rayed star (asterism) when illuminated by a single point light source.
Lore & History
Historically used in talismans in ancient Egypt, Rome, and Greece. Traditionally known as the stone of 'Unconditional Love,' it is associated with the Heart Chakra in modern crystal healing practices and symbolized reconciliation and peace in various cultures.
