Magnesite is a magnesium carbonate mineral, it occurs in rhombohedral crystals, and occasionally in other crystal forms. It is also found in granular, massive and fibrous habits. It forms in sediments, hydrothermal veins and metamorphic rocks. Magnesite is frequently white, but can also occur in shades of grey, yellow or brown. Some of the finest crystalline specimens of Magnesite come from Minas Gerais, Brazil.

Magnesite is said to be a powerful emotional balancer. It may be especially helpful for those who are under excessive stress or who are unable to release control.
Magnesite is considered to aid the body in releasing tension or stagnation. It may be ideal for muscle spasms, muscle adhesion, and chronic muscular tension due to stress.
