Boji
Boji (also Bojistein ) is a trade name and a registered trademark of the company Boji Inc. for a special variety of pyrite , more precisely a mineral aggregate or better a concretion of pyrite and limonite with a bulbous-spherical or lenticular appearance. In order to avoid the trade name, names such as Kiesball or Pop-Rock are occasionally used .
Education and Locations
Boji stones are secondary to the release of sulfur when organic materials decay in the mud of the seabed . In the absence of air, hydrogen sulfide combines with iron compounds to form pyrite concretions with a bulbous or spherical appearance. After the sludge has been compacted into clayey sediments , the nodules remain trapped in the rock until they are exposed again at a later point in time through weathering , as they are more resistant to weathering than mudstone . The pyrite concretion is transformed superficially into limonite by air oxygen . Similar to pyrite, boji stones also tend to decay over the course of decades to centuries due to the absorption of water and progressive oxidation , which becomes visible through sulphate efflorescence.
Large deposits of boyi stones can be found near Dongchuan in China and in the US states of Kansas , Nebraska , North and South Dakota .
use
Boji stones are mainly used as healing stones . Esotericists see them as "containers of energy centers" that can be activated by "caressing". More angular bojis are referred to as "male" and more smooth as "female" stones and are preferably used together.
