Rose Quartz
- Quartz species; hexagonal (trigonal) crystal system; chemical composition SiO2
- Rose Quartz – semitransparent to translucent pink, often very light in tone
Identification:
- Optic Character: DR uniaxial positive or AGG (depending on variety)
- Refractive Index: 1.544-1.553 (very constant)
- Birefringence: .009 (may not be detectable in aggregate varieties) Dispersion: .013
- Pleochroism: weak to strong, different tones of pink
- Ultraviolet Fluorescence: inert to weak purple (SW)
- Cause of Color: rose quartz – titanium and/or color centers
- Specific Gravity: 2.66 (+.03.-.02)
- Polish Luster: vitreous Fracture: conchoidal to uneven or granular (in aggregates)
Luster: vitreous - Cleavage: none
- Hardness: 7
- Toughness: good
Enhancements:
- Method: dyeing
Effect: produces vividly colored novelty stones, or imitations of more expensive stone emerald and ruby
Prevalence: common
Detection: appearance, magnification (dye concentrations), may show unusual fluorescence
Stability: fair to good, some dyes may fade
Special Care Instructions: avoid strong solvents and prolonged exposure to strong light
