🌋Obsidian is a volcanic glass found all over the world that is formed during the rapid cooling process of lava. Obsidian can range from opaque black to translucent and it can have a gold, silver, and rainbow sheen depending on the impurities present within the volcanic glass. In this video we showcase rainbow Obsidian. Layered rainbow Obsidian from Mexico gets its amazing vibrant color from inclusions of Hedenbergite nanorods. These micro inclusions create a thin-film interference of light resulting in beautiful and vibrant colors. Obsidian has been used for centuries because of its ability to be easily fractured into extremely sharp tools. It was also used as one of the earliest known mirrors because of its highly reflective nature.
