Obsidian Rainbow

Obsidian or volcanic glass is a material with a unique formation, during which hot lava cools rapidly, e.g. in water or on the Earth’s surface. The process is so fast that the individual minerals do not have enough time to crystalise. Our rainbow obsidian is dark with fine banded lines, and it comes from Mexico. If the stone is cut in the right way, the light refraction on its tiny little layers provides rainbow-like effects. If we look at its chemical structure, rainbow obsidian is a natural variety of volcanic silicate glass.
