Chromite is the main source of the metal chromium that is composed of iron, chromium, and oxygen. These minerals are the member of the Spinel group and share the same crystal structure but differ in composition.
Chromite is isomorphous with Magnesiochromite and because of their occurrence in the same environment, they can be easily confused with each other.
Let us learn more about Chromite.
Chromite is a brownish-black iron chromium oxide mineral that exhibits an isometric crystal system. As it is the only economic ore of chromium, it is extremely important.
It is quite a versatile element and is used in many different applications in the industries. These stones can stimulate and open up the base and sacral chakra. It helps to make significant changes in one's life, foster creativity, aid with positive thoughts, and promote stability in life.
In 1798, Louis Nicolas Vauquelin, a French pharmacist and chemist, originally named Chromite as "fer chromate alumine". Again in 1845, Wilhelm Haidinger, an Austrian mineralogist, name it "Chromite" in allusion to its composition. Fine specimens of these minerals are found in Turkey, Albania, Madagascar, South Africa, Zimbabwe, Canada, and Finland.
Chromite commonly occurs in metamorphic serpentine deposits, ultrabasic igneous rocks, and placer deposits. It also occurs in ultramafic portions of layered mafic igneous rocks as a cumulus mineral. These minerals can be found in association with other minerals like - Serpentine, Calcite, Chlorite, Talc, Olivine, Magnetite, Uvarovite.
The chemical formula of Chromite is Fe2+Cr3+2O4. These stones have a hardness of 5.5 according to the Mohs scale.
The color of Chromite varies from Brownish-Black to Greenish-Black.
The value of Chromite can vary anywhere from $15 to $40 according to its color and quality.
