Obsidian, known as volcanic glass, forms when molten lava cools rapidly, preventing crystals from forming. This process creates a smooth, glassy surface with sharp edges. Typically black or dark brown, obsidian consists mainly of silicon dioxide, similar to quartz but with unique properties due to its quick cooling.

Found in volcanic regions like the U.S. (Oregon, Arizona), Mexico, Italy, and Iceland, each deposit offers distinct colors and textures. Historically, ancient cultures like the Aztecs and Mayans valued obsidian for its sharpness, crafting tools, weapons, and ceremonial blades. Its beauty and practicality make obsidian a timeless gemstone with cultural significance worldwide.
