Also called Mt. St. Helen’s Obsidian aka Mt. St. Helen’s Peacock Obsidian aka Gaia Stone aka Helenite aka Emerald Obsidianite aka Obsidianite.
When I first saw this stuff, I was told it was Obsidian with Mt. St. Helen’s ash “introduced” into it. When anything is “introduced”? that means it is NOT naturally occurring.
The story was that it was reconstituted glass with Mt. St. Helen’s ash introduced into the process. Reconstituting is a process where the material is melted and all the impurities are removed then it is reformed. A partial description went like this…, “Mt St Helen Obsidian Rough. Fantastic Neon Blue color obsidian which is volcanic glass and is sometimes called Emerald Obsidianite…”
Now, when someone calls something “Obsidianite” instead of Obsidian….that is a red flag for me. They go on to say that the person making this adds the Neon Blue to Emerald coloring. Bottom line is that this is man-made, not nature made. It is not rare. It is not naturally occurring.
Again, Obsidian is amorphous, meaning it has no crystal structure, lacks form and is almost always opaque meaning light cannot pass through it (unless it is polished which can make it translucent, like polished Apache Tears). It is almost always dark in color (dark black, dark brown, dark green). Yes, it can have color, like Rainbow Obsidian, but that obsidian is dark black/brown with shimmers, bands or flashes of color, NEVER TRANSPARENT and NEVER BRIGHTLY COLORED.
