Obsidian is a natural volcanic glass formed by the rapid cooling of felsic lava, resulting in a smooth, glassy texture with no crystal structure. Known for its sharp conchoidal fracture, it was historically used for tools, weapons, and mirrors. It is primarily black but can appear in shades like red, brown, or sheen, frequently used in jewelry, art, and spiritual, grounding, or protective practices.
