Rainbow Obsidian Beads
While much obsidian is solid black, sometimes, this gemstone contains microscopic bubbles of air that create an interesting rainbow-colored sheen effect. When this glowing effect is present, the material is called rainbow obsidian.
Our rainbow obsidian beads are a velvety black color with a lustrous, but subtle sheen of green, purple, or orange, depending on the light. If you’re looking for black with an added twist, you’ll love this stone.
More About Rainbow Obsidian
Obsidian is a type of naturally formed glass that was originally expelled from a volcano as molten lava and then cooled very rapidly in the surrounding environment. This rapid cooling prevents an organized crystal structure from forming, so although obsidian is a hard material, in chemical terms, it is considered a liquid! From a geological perspective, most obsidian is a very young material – less than 20 million years old – as over time, it becomes transformed from glass into rock through a process called “devitrification”.
