Obsidian is a silica-rich volcanic rock. Different kinds of obsidian exist, varying due to the chemical composition of the rock. Obsidian is actually a natural glass. It forms during a silica-rich lava eruption with less than 3% water. Upon exiting the volcano, it cools very rapidly, freezing the crystallization process.
This can be likened to a piece of lava suddenly solidified as it emerges from the volcano. The direct consequence of this phenomenon is the rock's inability to crystallize. The result is the creation of a volcanic glass with a uniform texture, referred to as an amorphous mineral. Furthermore, obsidian has sharp edges and very thin blades. It is a natural mineral with a complex composition. Thus, obsidian is essentially composed of silicon dioxide, approximately 70% or more. Its fracture is conchoidal (i.e., grooved with curved and concentric striae) and its hardness is 5 to 5.5 on the Mohs scale. It possesses different colors and reflections due to the volcano where it was discovered and its various inclusions. It should be noted that each deposit, linked to a volcano, provides a different obsidian. Green, brown, gray or black, it can have reflections that are sometimes golden, silver, or even all the colors of the rainbow (an effect produced by the presence of hematites or magnesites). It also happens that two colors of obsidian mix. This is pure and basic obsidian. Composed of over 70% silica, it owes its beautiful dark color to the presence of iron. It has almost no inclusions except for a few nanoparticles of magnetite. During archaeological excavations, it often involves discoveries of tools and weapons made of black obsidian. The legend of young Obsid highlights the discovery of an extremely sharp black obsidian on the ground. Black obsidian is a smooth, shiny stone, similar to glass due to its brilliant and reflective surface. This stone can break into fragments with curved edges. This characteristic is ideal for making cutting tools. Nowadays, black obsidian is frequently used in the manufacture of jewelry and ornamental objects. This stone has powerful benefits in lithotherapy.This piece is made of natural black obsidian. Discover all the virtues and properties of this fascinating stone.
