Physical properties
Hardness: 6.0-6.5 (Mohs scale); Color: Creamy white to pale celadon green; Luster: Greasy to waxy; Structure: Interlocking microcrystalline fibers; Specific Gravity: 2.90–3.03.
Formation & geological history
Formed through the regional metamorphism of magnesium-rich limestones or dolomites, or from the hydrothermal alteration of ultramafic rocks. Nephrite is exceptionally tough due to its felted fibrous structure.
Uses & applications
Primarily used for decorative carvings, jewelry, figurines, and historically for tools and weapons due to its extreme toughness.
Geological facts
Nephrite was the original 'Jade' of ancient China. It is much tougher than steel and was often called the 'Stone of Heaven.' This specific carving of an elephant represents strength, wisdom, and good luck in many cultures.
Field identification & locations
Identify by its waxy luster and extreme toughness (resistant to fracturing). It is often found in riverbeds as boulders. It feels heavier than it looks (high density) and remains cool to the touch.
