Obsidian: Meaning, Properties, and Uses
If you’ve ever held a piece of obsidian, you know it’s unlike any other stone. Jet-black, glossy, and razor-sharp, this volcanic glass has fascinated humans for centuries. But what exactly is obsidian, and why is it so special?
In this guide, we’ll explore its meaning, properties, and practical uses—whether you’re a crystal enthusiast, a history buff, or just curious about this unique mineral.
What Is Obsidian?
Obsidian is a naturally occurring volcanic glass formed when lava cools rapidly, preventing crystal growth. The result? A smooth, shiny rock that fractures into sharp edges—so sharp, in fact, that ancient civilizations used it to make knives, arrowheads, and surgical tools.
Unlike most gemstones, obsidian isn’t a true mineral because it lacks a crystalline structure. Instead, it’s classified as a mineraloid. Its deep black color is the most common, but variations like rainbow, mahogany, and snowflake obsidian exist due to different mineral inclusions.
