Throughout the prehistoric period, obsidian stone was used to craft tools and weapons. This igneous rock has existed for over 36,000 years. Still exploited by some Indian peoples, Obsidian is a stone that served the first peoples in their development. Though it can be found in various parts of the world, obsidian stone is considered the stone of Mexico. This is because the majority of the extraction was carried out there for millennia. Since its existence, obsidian stone has been located primarily on the Asian, African and European continents. However, the first deposits date back to 21,000 years before Christ and are located in the United States and Mexico.
Obsidian stone was named after ‘Obsius’, an ancient Roman explorer who discovered it in Ethiopia. Obsidian is a volcanic stone and can occur in black, red, grey or even blackish-green varieties. This stone is extremely rich in silica. It can be both translucent but also transparent, with a vitreous luster and a unique texture.
Characterised by a mixture of sharp and smooth fractures, obsidian stone is deemed conchoidal. It has a rather high hardness as it varies between 7 and 7.5 on the Mohs scale, which can allow it to scratch crystals such as glass, for example. Known for its uniqueness and abundance around volcanoes, Obsidian stone can be found in Armenia, the United States, Japan, Iceland, Mexico and Peru.
In litho therapy, obsidian stone is to be used with caution due to its powerful properties. Obsidian is a protective stone of powerful strength that acts very quickly. Well suited for vulnerable people, it helps protect against negative energies. Wearing an obsidian pendant, for example, can grant the wearer a protective shield.
Some therapists place Obsidian stone in their hands and at the level of the root chakra. It allows them to protect their mind from instability. Obsidian also mitigates many pains, such as cramps or other joint pains. It also helps to ward off the surrounding negative energies. If you place obsidian near your bed at night, it can dissipate all mental tensions.
