Physical properties
Hardness: 2.5–5 Mohs; Color: pale yellowish-green to lime green; Luster: waxy to greasy; Crystal Structure: Monoclinic; Cleavage: poor; Specific Gravity: 2.44–2.62.
Formation & geological history
Formed through serpentinization, a metamorphic process where ultramafic rocks from the Earth's mantle are altered by hydrothermal fluids at low temperatures.
Uses & applications
Commonly used in jewelry, small carvings, and as tumbled stones for metaphysical purposes or decorative accents.
Geological facts
Despite the trade name 'New Jade', this mineral is actually a variety of serpentine and not a true jade (nephrite or jadeite). It has been used for centuries as a substitute for jade due to its similar appearance.
Field identification & locations
Identify by its characteristic waxy luster and relative softness compared to true jade (which is 6-7 on Mohs scale). It can be scratched by a steel blade. Found commonly in China, Afghanistan, and the USA.
