Physical properties
Hardness: 2-4 (garnierite) to 7 (matrix), Color: bright green to pale lime streaks in tan/brown matrix, Luster: Vitreous to dull, Crystal Structure: Monoclinic, Cleavage: None
Formation & geological history
Formed through the intense chemical weathering of ultramafic rocks (lateritization) like serpentinites and peridotites in tropical or subtropical climates.
Uses & applications
Primarily used as a minor ore of nickel and as a decorative stone or 'healing crystal' by collectors. Frequently carved into towers or spheres.
Geological facts
The term 'Garnierite' is not a single mineral species but a generic name for various secondary nickel-magnesium silicates. It was named after Jules Garnier who discovered it in New Caledonia.
Field identification & locations
Identify by its distinctive neon green color against a stony matrix. It is commonly found in New Caledonia, Madagascar, and parts of the United States like Oregon.
