Description

Twilight Obsidianite

This beautiful color-change obsidian gem is created from silicon-aluminum volcanic rock dust or “ash” ejected from Mt St Helens. Very similar to the Emerald Obsidianite but with the chemicals that made it green removed. The trace elements of cobalt, manganese, titanium and potassium fuse together at 2700 degrees Fahrenheit to form the beautiful purple color. This stone changes color under different lighting. Normally its purple (similar to tanzanite), while fluorescent light will change it to light blue (similar to blue topaz).
