Garnierite

Garnierite is named Jules Garnier who first discovered it 1864 in New Caledonia. It is a generic name for a green nickel ore which has formed as a result of lateritic weathering of ultramafic rocks. Garnierite is not a valid mineral name according to the Commission on New Minerals, Nomenclature and Classification (CNMNC), therefore no definite composition or formula has been universally adopted.

Garnierite is a fine grained mineral with poor crystalline structure. The colour ranges from light yellow-green to dark green.

Garnierite can be used for carvings and ornamental objects.
