Obsidian is a naturally occurring volcanic glass formed when silica-rich magma cools extremely rapidly. Because of this swift cooling process, no crystals develop; instead, a deep black, glass-like structure is created, capable of producing exceptionally sharp fracture edges.
Obsidian is found in volcanically active regions around the world, including Central America, Japan, Iceland and the Mediterranean. For thousands of years, it has been valued by cultures across the globe as a material, a trade good and a ritual object.
Each piece of obsidian is a unique testament to geological forces and natural origin.
