About This Crystal
A translucent to semi-opaque pale pink to deep rose-red variety of quartz. This specimen is a rounded, tumbled stone showing a vitreous to waxy luster and characteristic cloudiness caused by microscopic inclusions.
Physical Characteristics
Color: Pink; Streak: White; Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.65; Fluorescence: Occasionally weak purple under UV light.
Optical Properties
Refractive Index: 1.544–1.553; Birefringence: 0.009; Doubly refractive; occasionally displays asterism (six-rayed star) due to rutile inclusions.
Hardness & Durability
Origin Region
Major sources include Brazil, Madagascar, South Africa, India, and the United States (South Dakota)
Hardness & Durability
Mohs hardness: 7; Good toughness; very durable for jewelry but can be brittle if it has internal fractures.
Care & Maintenance
Wash with warm soapy water; avoid prolonged exposure to direct sunlight as colors may fade; store separately from harder gems like diamond or sapphire.
Rarity & Value
Common; value is determined by color intensity and clarity. Treatments like irradiation or dyeing are sometimes used to enhance color.
Special Characteristics
Some specimens exhibit 'star rose quartz' (asterism) when cut into cabochons; contains microscopic fibrous inclusions of dumortierite or rutile.
Lore & History
Historically used in ancient Egypt and Rome for talismans. Culturally known as the 'Stone of Love,' associated with the heart chakra and emotional healing.
