Obsidian is a volcanic rock rich in silica. Different types of obsidian exist. They differ due to the chemical composition of the rock. Obsidian is actually a natural glass. It is formed during an eruption of silica-rich lava with less than 3% water. Upon exiting the volcano, it cools very quickly, freezing the crystallization process.

This can be compared to a piece of lava suddenly freezing as it leaves the volcano.
The direct consequence of this phenomenon is the inability of the rock to crystallize. The result is the creation of a volcanic glass with a uniform texture and which is called an amorphous mineral. In addition, obsidian has sharp edges and blades of great finesse.
It is a natural mineral with a complex composition. Thus, obsidian is essentially composed of silicon dioxide, about 70%, or more. Its fracture is conchoidal (i.e. furrowed with curved and concentric striations) and its hardness is 5 to 5.5 on the Mohs scale. It has different colors, different 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 sometimes have reflections that are golden, silvery, or even all the colors of the rainbow (effect produced by the presence of hematites or magnesite).
It also happens that two colors of obsidian mix together.
This is pure and basic obsidian. Composed of more than 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, these are often discoveries of tools and weapons made of black obsidian.
The legend of the young Obsidian highlights the discovery of a black obsidian on the ground, extremely sharp. Black obsidian is a smooth and shiny stone, similar to glass due to its shiny and reflective surface. This stone can break into fragments with curved edges. This particularity is ideal for making cutting objects. Nowadays, black obsidian is frequently used in the manufacture of jewelry and ornamental objects.
