What is Obsidian Rock Used For?

Obsidian is a naturally occurring volcanic glass that forms when lava cools rapidly. Due to its unique properties, obsidian has been an important material used throughout human history for a variety of purposes. Here are some of the main uses of obsidian rock:


One of the earliest and most common uses of obsidian was for crafting stone tools like knives, spear points, scrapers and arrowheads. Obsidian can be fractured to produce extremely sharp edges, which made it a highly useful material before the advent of metals. In fact, obsidian tools and weapons were pivotal for early hunter-gatherer societies. Today, obsidian scalpels are still used for some specialty surgeries because of their superior sharpness.


Obsidian’s beautiful sheen has made it a popular gemstone used in jewelry for thousands of years. Ancient civilizations like the Aztecs, Mayans and Romans fashioned obsidian into beads, mirrors and embellishments. Modern jewelers appreciate its color variations and natural glassy texture. Obsidian is cut and polished into rings, pendants, earrings and more. Certain types like rainbow, golden and snowflake obsidian are especially prized.

Spiritual Meaning

In many ancient cultures, obsidian was believed to have spiritual powers or offer protection. It has been used in mystical and healing practices, ceremony and amulets across many societies from Mexico to Greece. Some cultures thought obsidian could shield against negativity or evil spirits. Today, obsidian remains popular in new age crystal healing practices and metaphysical stone meaning.


Slabbed and tumbled pieces of obsidian make for popular interior decor elements. Its dark glossy appearance resembles natural glass. Obsidian works well in stone veneers, fireplace surrounds, coasters and table centerpieces. It also comes in sheets used for wall tiles and flooring. Decorative obsidian ornaments, bowls and figurines are also common gifts and collectibles.


Obsidian was used for various medical treatments by ancient peoples. The Aztecs ground it up as an ingredient in medicinal tonics. Some Native American tribes used very finely powdered obsidian in a poultice for treating open wounds because of its antiseptic effects. Today, obsidian is sometimes used in holistic healing, such as in crystal massage wands. However, its medical uses are limited.


Obsidian has served as an artistic medium since prehistoric times when it was carved into figurines or decorative objects, or chipped into early mirrors. Ancient craftsmen also used it to create mosaics and inlays. Recently, obsidian has become popular for modern sculptures, mixed media mosaics and abstract paintings. Its natural sculptural quality and metallic colors provide inspiration. When fractured, it reveals beautiful banding and patterns.

In summary, obsidian is an extraordinarily versatile natural material that has been utilized for cutting tools and weapons, ornamental objects, spiritual meaning, decorative touches, primitive medicine and artistic inspiration throughout antiquity. Even today, obsidian continues to hold importance in jewelry, healing, art and decor due its allure, hardness and glass-like sheen.
