Mahogany Obsidian
Volcanic Glass – brown with black flecks.
Obsidian (also known as Lava Glass) is formed when minerals in the ground are exposed to exceedingly high temperatures until they turn to glass. It is found on the walls of lava tubes, coating the inside of the tunnels as magma is transported through the Earth’s crust. When thinly sliced and highly polished, it becomes a translucent stone with Quartz like qualities.
Mahogany Obsidian is named after the textures across the surface of a highly polished specimen. The unusual brown colouring is formed from inclusion of Haematite and Iron.
Obsidian is generally used as a protective stone, as it is known to calm negative energies. It is commonly thought to protect from physical and emotional harm, helping to find a sense of grounding in times of distress.
