Grunerite
Grunerite is a monoclinic amphibole mineral with the chemical formula containing iron, silicon, oxygen, and hydroxide. It belongs to the amphibole group and is classified under the tectosilicate class in the Strunz system (9.DE.05). The mineral typically exhibits a prismatic monoclinic crystal habit and is characterized by a dark green to black color, a vitreous to subvitreous luster, a hardness of approximately 5 to 6 on the Mohs scale, and a density of around 3.0 to 3.4 g/cm³. Grunerite is commonly found in metamorphic and igneous environments, and it is known for its fibrous or prismatic crystal forms.
Overview
Grunerite is a monoclinic amphibole mineral with the chemical formula containing iron, silicon, oxygen, and hydroxide. It belongs to the amphibole group and is classified under the tectosilicate class in the Strunz system (9.DE.05).

Grunerite is commonly found in metamorphic and igneous environments, and it is known for its fibrous or prismatic crystal forms.
Etymology
Grunerite is named after Emmanuel-Louis Gruner, a French mineralogist. The mineral was officially redefined by the International Mineralogical Association (IMA).
Geological genesis
As an amphibole mineral, grunerite is typically of metamorphic or igneous origin. It forms in environments where high-pressure and high-temperature conditions facilitate the crystallization of silicate minerals, particularly in metamorphosed mafic rocks.
Spiritual meaning and crystal therapy
Spiritual meaning
Grunerite is traditionally associated with strength and protection, often seen as a grounding stone that supports spiritual growth and emotional resilience.
Esoteric properties
Grunerite is said to offer calming and grounding properties, helping to dispel negative energies and promote a sense of inner stability and clarity.
Associated chakra
Grunerite is traditionally associated with the root chakra due to its grounding properties, helping to anchor energy and foster a sense of security and connection to the earth.
Crystal therapy use
In crystal therapy, grunerite is often used by placing it near the feet or sitting on it to ground energy. It can also be worn as jewelry or carried for ongoing support.
