Black Obsidian

Clarity and protection in volcanic glass.

Black Obsidian is volcanic glass that forms when lava cools too quickly for crystals to develop. Unlike crystalline minerals, it's amorphous. This rapid formation gives it a distinctive glossy surface and sharp edges that have made it valuable for tools and ritual use across cultures for thousands of years. We source raw specimens from small-scale operations across several volcanic regions, with Argentina as our primary source alongside Mexico and the United States, chosen for clarity, finish, and untreated character. Many people work with black obsidian for grounding, protection, and the clear mirror-like quality that invites self-reflection.
