Natural Black Obsidian Spheres | Polished Volcanic Glass Crystal Spheres

Natural Black Obsidian Spheres

These polished black obsidian spheres feature a deep jet-black finish and glass-like luster formed from rapidly cooling volcanic lava. Their smooth surface and reflective shine make them striking display pieces despite their smaller size.

Unlike most minerals, obsidian is a natural volcanic glass rather than a true crystal, forming when silica-rich lava cools too quickly for crystals to develop. The result is the rich black color and mirror-like polish that have made obsidian one of the world’s most recognizable volcanic materials.
