Refractive index ranges from 1.606 to 1.667. Birefringence is weak. It is doubly refractive and typically translucent to opaque with a soft, glowing internal luminescence.
Hardness & Durability
Origin Region
Myanmar (Burma), China, Guatemala, Russia, Canada, United States
Hardness & Durability
Mohs hardness is 6 to 7 for jadeite and 6 to 6.5 for nephrite. Exceptionally tough due to its interlocking microfibrous or granular structure, making it highly resistant to breakage and ideal for intricate carvings.
Care & Maintenance
Clean with warm soapy water and a soft cloth. Avoid harsh chemical cleaners and ultrasonic cleaners. Store away from harder gems to prevent scratching.
Rarity & Value
Common to Rare depending on quality, color intensity, and translucency. Imperial green jade is extremely rare and valuable, while pale, mottled carvings are more common and affordable.
Special Characteristics
Renowned for its unmatched toughness rather than cleavage, interlocking crystal structure provides immense durability, highly prized for fine artistic carvings across Asian cultures.
Lore & History
Deeply revered in Chinese history as the 'Stone of Heaven', symbolizing purity, wisdom, and status. Used for thousands of years in ancient burial suits, ritual objects, and jewelry. Associated with the Heart Chakra in modern metaphysical practices to promote emotional balance and prosperity.
