Jadeite
Jadeite · Precious Gemstone and Decorative Stone
Crystal System
Monoclinic; typically forms massive, compact aggregates or granular structures
Mineral Group
Silicates (Inosilicates, Pyroxene group)
Chemical Formula
NaAlSi2O6
Formation Process
Metamorphic, occurring in subduction zone environments under extremely high pressure and relatively low temperatures
About This Crystal
The specimen is a strung bracelet composed of spherical polished beads exhibiting a pale to medium greyish-green color. The beads show a sub-translucent to translucent appearance with a characteristic microcrystalline or granular texture, displaying vitreous to greasy luster upon polishing and slight mottled color zoning.
Physical Characteristics
Color ranges from pale green to bluish-green; white streak; cleavage is good in two directions (prismatic); fracture is splintery to uneven; specific gravity is approximately 3.24 to 3.43; tenacity is exceptionally tough due to its interlocking microfibrous structure.
Optical Properties
Refractive index ranges from 1.654 to 1.667; birefringence is low (0.012 to 0.020); biaxial positive; generally displays a vitreous to greasy luster with a characteristic mottled or fibrous internal appearance.
Hardness & Durability
Origin Region
Myanmar (Burma), Guatemala, Russia, and California, USA; formed in high-pressure, low-temperature metamorphic environments
Hardness & Durability
Mohs hardness is 6.5 to 7; exceptionally high toughness making it extremely resistant to breaking despite moderate hardness; highly durable for daily jewelry wear.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid harsh chemicals, ultrasonic cleaners, and extreme heat; store separately from harder gems to prevent scratching.
Rarity & Value
Varies widely from common for lower-grade commercial material to extremely rare for top-quality 'Imperial Jade'; value depends heavily on color intensity, translucency, texture, and lack of chemical treatments.
Special Characteristics
Renowned for its incredible toughness due to microcrystalline interlocking fibers (interwoven granular habit); displays unique fibrous or mottled internal patterns under magnification.
Lore & History
Deeply significant in Chinese, Mesoamerican, and Maori cultures, symbolizing purity, nobility, and protection. Often associated with the Heart Chakra in modern metaphysical practices, representing abundance, emotional balance, and harmony.
