Black Obsidian is a natural glass formed by the sudden cooling of magma from volcanic lava flows, and is an amorphous gemstone whose main component is silica.
During the formation process, the magma of silica quickly condenses into blocks as the temperature at the periphery of the karst drops rapidly and cools quickly, and black obsidian usually occurs at the periphery of the lava or at the foot of the volcano near the sea. Because of the unique formation process of obsidian, it contains 1-2% water within its crystals.
