Obsidian is an intriguing igneous rock with a glassy texture, typically jet-black in color. It forms when lava with a high silica content cools quickly, resulting in a beautiful and unique rock that you can treasure. The presence of hematite (iron oxide) can produce red and brown varieties of obsidian, while tiny gas bubbles may create a golden sheen.
