Obsidian is instantly recognisable for its dark, glass-like surface. Geologically it is not a crystal in the usual sense but natural volcanic glass, formed when silica-rich lava cools too quickly for crystals to develop.

What is obsidian?

Obsidian is naturally occurring volcanic glass. Rapid cooling creates its characteristic glassy structure. Broken obsidian can form extremely sharp edges, which is one reason people have used it for cutting tools for thousands of years.

Black obsidian meaning

In crystal and spiritual traditions, black obsidian is commonly associated with protection, grounding, clear boundaries and self-reflection. Its deep black appearance also makes it popular simply as a decorative stone.

How to use obsidian

A raw piece can be displayed on a shelf, altar or alongside other stones. In personal practices, obsidian may be used as a physical reminder to pause, reflect and maintain boundaries.

How to clean and care for obsidian

Its glassy surface can scratch and broken edges can be sharp. Wipe it with a soft dry or slightly damp cloth and avoid dropping it onto hard surfaces.
