Rose Quartz
Quartz var. Rose Quartz · Semi-Precious Gemstone and Decorative Stone
Crystal System
Trigonal, typically forms as massive or granular aggregates; distinct crystals are rare
Mineral Group
Silicates (Tectosilicates)
Chemical Formula
SiO2
Formation Process
Primarily forms in pegmatites during the late stages of magmatic crystallization, as well as in hydrothermal veins at moderate temperatures
About This Crystal
A polished sphere of pale to medium pink quartz, exhibiting translucent to semi-transparent clarity with internal cloudiness, micro-fractures, and a vitreous to waxy luster
Physical Characteristics
Pink body color, white streak, conchoidal fracture, no true cleavage, specific gravity of approximately 2.65, brittle tenacity, and generally inert under UV light
Optical Properties
Singly or doubly refractive with a refractive index of 1.544-1.553, low birefringence, and occasionally exhibits asterism (star effect) due to microscopic fibrous inclusions
Hardness & Durability
Origin Region
Madagascar, Brazil, United States, South Africa, and India; found primarily in pegmatites and hydrothermal veins
Hardness & Durability
Mohs hardness of 7, making it durable for daily wear in jewelry, though prone to fracturing if dropped due to lack of cleavage
Care & Maintenance
Clean with warm soapy water using a soft cloth; avoid harsh chemicals, prolonged direct sunlight which may cause fading, and ultrasonic or steam cleaners if fractures are present
Rarity & Value
Common and widely available; value is determined by color saturation, transparency, and size, with prices ranging from affordable for polished spheres to moderate for high-clarity gem-grade material
Special Characteristics
Often contains microscopic dumortierite or fibrous inclusions that can produce chatoyancy or asterism when properly cut as cabochons; exhibits piezoelectric properties
Lore & History
Historically used by ancient civilizations such as the Assyrians and Egyptians for talismans and amulets; widely known in modern crystal healing as the stone of unconditional love and associated with the Heart Chakra
