Black Obsidian 50mm Sphere with Tree of Life Emblem

A striking Black Obsidian 50mm sphere with a Tree of Life emblem — a powerful combination of volcanic earth energy and one of the world’s most enduring spiritual symbols.

Geology: Obsidian is a naturally occurring volcanic glass formed when silica-rich lava cools rapidly, preventing crystal growth. Its deep, mirror-like black colour comes from iron and magnesium content. Found near volcanic regions worldwide — including Mexico, Iceland, and the USA — it has been used by humans for tools, weapons, and ceremonial objects for thousands of years.

Metaphysical Properties:

In crystal healing traditions, Black Obsidian is a powerful protective and grounding stone — associated with the root chakra, psychic protection, truth, and the release of negative energy. The Tree of Life symbol represents growth, strength, connection between earth and cosmos, and the cycle of life — making this sphere a meaningful piece for meditation, altar work, or as a thoughtful gift.

As a natural volcanic glass, minor surface variations and inclusions are characteristic of genuine obsidian. Each sphere is unique.
