Physical properties

Formation & geological history

Formed from the alteration of ultramafic rocks (rich in magnesium and iron) through hydrothermal processes. Geological Age: Varies depending on location, can be found in rocks ranging from Proterozoic to Cenozoic.

Uses & applications

Primarily used in carvings, ornamental objects, and jewelry (cabochons, beads). Less commonly used in industry due to its relative softness compared to other silicates.

Geological facts

Also known as 'New Jade' or 'South African Jade', although it's not true jade. It's often carved into ornamental objects and beads due to its appealing color and relatively good hardness.

Field identification & locations

To identify in the field: Look for its waxy luster, often translucent nature, and greenish color. It can be found in metamorphic terrains where ultramafic rocks are present. Common locations: Serpentine is found worldwide, with notable deposits in the USA (California, Pennsylvania), Canada, Russia, Afghanistan, and New Zealand. Chrysoprase is found in Australia, Brazil, Russia, and the USA. Tips for collectors: Check for translucency and color consistency. True jade will be much harder and denser.
