Physical properties

Hardness: 4 to 6 on Mohs scale; Color: Light green to yellowish-green with mottled clouds; Luster: Waxy to greasy; Structure: Massive or fibrous; Specific Gravity: 2.44 to 2.62.

Formation & geological history

Formed through the process of serpentinization, where ultramafic rocks (like peridotite) undergo low-temperature hydrothermal metamorphism at tectonic plate boundaries.

Uses & applications

Commonly used for ornamental carvings, polished eggs/spheres, beads, jewelry, and as a less expensive alternative to true jadeite or nephrite.

Geological facts

While often marketed as 'New Jade,' it is actually a variety of the mineral serpentine. It has been used since ancient times for amulets and seals because it is relatively easy to carve.

Field identification & locations

Identify by its waxy luster and distinctive palish-green color. In the field, it is often found in 'serpentinite belts.' It is softer than true jade (nephrite/jadeite) and will be scratched by a steel knife.
