About This Crystal
The image shows two beaded bracelets held in a hand. One strand consists of spherical pink beads displaying an intense, web-like internal fracture pattern (crackle quartz) infused with pink dye. The other strand features translucent, pale green beads with a soft, glittering shimmer caused by microscopic mineral inclusions typical of green aventurine.
Physical Characteristics
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, white streak, specific gravity around 2.65
Optical Properties
Singly or doubly refractive depending on aggregate structure, strong uneven color distribution due to artificial dying in the pink beads, and a metallic sheen (aventurescence) in the green beads
Hardness & Durability
Origin Region
Globally sourced, heavily processed and manufactured globally
Hardness & Durability
Mohs hardness of 7, making it durable for daily wear, though thermal shock treatments (cracking) make the pink beads more fragile to impact
Care & Maintenance
Clean with warm soapy water, avoid harsh chemicals and ultrasonic cleaners especially for dyed varieties which may bleed color
Rarity & Value
Common and inexpensive, highly accessible in commercial jewelry markets
Special Characteristics
Artificial crackle pattern and dye in the pink quartz; natural fuchsite flake inclusions causing aventurescence in the green quartz
Lore & History
Often utilized in modern crystal healing for emotional balance and heart chakra alignment, though these properties are traditional beliefs rather than scientific facts
