About This Crystal
The bracelet features tumbled chip beads of deep blue and white mottled sodalite interspersed with clear, transparent to translucent quartz crystals, separated by metallic spacer beads inset with purple and dark rhinestones.
Physical Characteristics
Colors range from royal blue and white to transparent clear. Streak is white for both minerals. Cleavage is distinct in sodalite and absent in quartz. Fracture is conchoidal for quartz and uneven for sodalite. Specific gravity is approximately 2.3 for sodalite and 2.65 for quartz.
Optical Properties
Sodalite is isotropic (singly refractive), while quartz is uniaxial positive (doubly refractive). Both exhibit a vitreous to greasy luster.
Hardness & Durability
Origin Region
Worldwide, notably Brazil, India, and Canada
Hardness & Durability
Sodalite has a Mohs hardness of 5.5 to 6, while quartz has a hardness of 7. Durability is moderate; the softer sodalite can be scratched by harder minerals and quartz components.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid harsh chemical cleaners, ultrasonic cleaners, and prolonged exposure to direct sunlight which can fade certain minerals.
Rarity & Value
Common and widely accessible. Value is low to moderate, determined largely by the craftsmanship of the jewelry piece rather than gemstone rarity.
Special Characteristics
Sodalite may exhibit orange-yellow fluorescence under ultraviolet light due to trace components.
Lore & History
Sodalite is traditionally associated with enhancing logic, intuition, and emotional balance, linked primarily with the throat and third eye chakras, while clear quartz is considered a master healer stone.
