Jadeite
Jadeite var. Imperial Jade · Precious Gemstone
Crystal System
Monoclinic; massive, microcrystalline aggregate habit
Mineral Group
Silicates; Pyroxene subgroup
Chemical Formula
NaAlSi2O6
Formation Process
Metamorphic, occurring in subduction zone environments involving high pressure and relatively low temperatures where sodium- and aluminum-rich fluids interact with serpentinite
About This Crystal
The featured specimen is a vividly saturated, translucent apple-to-emerald green carved jadeite piece, traditionally shaped into a symbolic figure (such as a Buddha or deity) and accented with a halo of vivid pinkish-red rubies set in gold. It displays a vitreous to greasy luster, fine fibrous microcrystalline texture, and exceptional translucency.
Physical Characteristics
Color ranges from bright apple green to vibrant emerald green with white streak. Cleavage is good on two directions at nearly right angles (prismatic), but typically seen as a tough, splintery-to-granular fracture. Specific gravity is approximately 3.24 to 3.43. Tenacity is exceptionally tough due to its interlocking fibrous structure.
Optical Properties
Biaxial (+) with refractive indices ranging between 1.654 and 1.667. Exhibits slight birefringence of around 0.012 to 0.020 and weak pleochroism. Translucency can range from semi-opaque to highly translucent, creating a rich, glowing visual depth known as "water" in trade terminology.
Hardness & Durability
Origin Region
Myanmar (Burma), Guatemala, Russia, and Japan; typically forms in metamorphic serpentinite belts under high-pressure, low-temperature conditions
Hardness & Durability
Mohs hardness is 6.5 to 7. Despite a hardness comparable to quartz, jadeite possesses extreme toughness—making it exceptionally resistant to breakage due to its tightly interwoven microcrystalline mineral fibers.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid harsh chemical cleaners, ultrasonic cleaners, and steam cleaners. Store separately from harder gemstones to prevent scratching gold settings or adjacent stones. Generally stable and not prone to fading in sunlight.
Rarity & Value
Top-quality vibrant green imperial jadeite is extremely rare and among the most valuable gemstones in the world, often commanding high prices at auction. Treatments such as polymer impregnation (Type B) and dyeing (Type C) are common in lower grades, while untreated material (Type A) commands a premium.
Special Characteristics
Possesses a characteristic interlocking microcrystalline structure that yields extraordinary toughness. High-grade specimens exhibit a characteristic inner glow or translucency referred to as "chong" or depth of water.
Lore & History
Historically revered in ancient Chinese, Mesoamerican, and Maori cultures as a royal stone symbolizing purity, protection, wisdom, and status. In modern crystal healing, it is traditionally associated with the heart chakra, attracting good fortune, harmony, and emotional balance, though these are cultural beliefs rather than scientific facts.
