Obsidian: Nature’s Volcanic Glass Obsidian is a naturally occurring volcanic glass formed when lava cools rapidly without crystallizing. It is usually black but can also appear in shades of brown, red, or green due to mineral impurities. Key Properties: Sharp Edges: Used for ancient tools and modern surgical blades. Metaphysical Uses: Believed to offer protection and clarity. Fragile Yet Durable: Hard but brittle, breaking with a conchoidal fracture. Where to Find It: Major deposits exist in the U.S., Mexico, Iceland, and Japan. Obsidian has been valued for centuries in weaponry, jewelry, and spiritual practices, making it both a historical and scientific marvel.
