Gahnite
Gahnite is a cubic mineral with the chemical formula zinc aluminum oxide (ZnAl2O4). It belongs to the spinel group of minerals and is classified as a normal spinel structure. Gahnite crystallizes in the cubic crystal system and is characterized by a grey streak and a vitreous luster. It typically exhibits a hardness of 7.5 to 8 on the Mohs scale and has a relatively high density. The mineral is notable for its isometric symmetry and is commonly found in association with other spinel-group minerals. It is grouped under the Strunz classification 4.BB.05 and the Dana classification 7.2.1.4.

Overview
Gahnite is a cubic mineral with the chemical formula zinc aluminum oxide (ZnAl2O4). It belongs to the spinel group of minerals and is classified as a normal spinel structure.

It is grouped under the Strunz classification 4.BB.05 and the Dana classification 7.2.1.4.
Etymology
Gahnite is named after Johan Gottlieb Gahn, a Swedish mineralogist and chemist who made significant contributions to the study of minerals in the 18th century.
Geological genesis
As a member of the spinel group, gahnite typically forms in high-temperature and high-pressure environments. It is commonly associated with igneous and metamorphic processes, particularly in ultramafic and mafic rocks where aluminum and zinc are present in sufficient quantities.
Spiritual meaning and crystal therapy
