Jadeite Jade
Jadeite · Precious Gemstone
Crystal System
Monoclinic; massive, microcrystalline aggregate habit
Mineral Group
Silicates (Inosilicate)
Chemical Formula
NaAlSi2O6
Formation Process
Metamorphic; forms in subduction zone environments under high-pressure, low-temperature metamorphic conditions involving sodium-rich fluids
About This Crystal
The specimen is a beaded stretch bracelet consisting of spherical, polished beads featuring a muted grayish-green to pale bluish-green color, typical of natural commercial-grade jadeite. The beads exhibit a translucent to sub-translucent appearance with a vitreous to waxy luster, showing subtle mottling and internal fibrous or granular structures.
Physical Characteristics
Color: Muted grayish-green; Streak: White; Cleavage: Good in two directions (often indistinct in massive forms); Fracture: Splintery to uneven; Specific Gravity: 3.24 to 3.43; Tenacity: Extremely tough due to its interlocking microcrystalline structure
Optical Properties
Refractive Index: 1.654 to 1.667; Birefringence: 0.012 to 0.020; Optically biaxial (+); usually displays a characteristic mottled or fibrous texture under magnification
Hardness & Durability
Origin Region
Myanmar (Burma), Guatemala, Russia, and Japan; typically forms in metamorphic environments under high pressure and low temperature
Hardness & Durability
Mohs Hardness: 6.5 to 7.0; Exceptional toughness (interlocking fibrous crystals make it extremely resistant to breaking, harder to break than quartz); excellent durability for everyday jewelry wear
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh chemicals, ultrasonic cleaners, and extreme heat; store separately to prevent scratching softer stones
Rarity & Value
Uncommon to Rare depending on color saturation, translucency, and texture; high-grade imperial jadeite is extremely valuable, while standard commercial grayish-green material is moderately priced
Special Characteristics
Interlocking microcrystalline mineral aggregate structure giving it legendary toughness; subtle natural mottling and fibrous internal textures
Lore & History
Historically revered in ancient Chinese, Mesoamerican, and Maori cultures as a stone of nobility, protection, and luck; associated with the Heart Chakra in modern crystal healing traditions, symbolizing purity, serenity, and abundance
