Jacobsite
Jacobsite is a mineral with the chemical formula manganese(II) iron(III) oxide, MnFe2O4. It belongs to the cubic crystal system and has a space group of Fd-3m. Classified as a spinel-group mineral, jacobsite is a normal spinel structure with divalent and trivalent cations. It typically exhibits a metallic luster, a black to dark gray color, and a hardness of approximately 5.5 to 6 on the Mohs scale. Its density is relatively high, ranging from 4.6 to 5.2 g/cm³. Jacobsite is known for its magnetic properties and is commonly found in metamorphic and igneous rocks.

Jacobsite is known for its magnetic properties and is commonly found in metamorphic and igneous rocks.
Etymology
Jacobsite is named after the Jakobsberg mine, the type locality where it was first identified.
Geological genesis
As a spinel-group mineral, jacobsite typically forms in metamorphic and igneous environments where conditions favor the crystallization of oxide minerals.
Occurrence
Jacobsite is found in metamorphic and igneous rocks, particularly in association with other oxide minerals. Its type locality is the Jakobsberg mine.
Spiritual meaning and crystal therapy
Spiritual meaning
Jacobsite is traditionally associated with grounding and protection, helping to connect one to the Earth's energy. It is seen as a stone of strength and resilience, supporting spiritual growth and inner stability.
