This naturally-occurring volcanic glass is formed as an extrusive igneous rock. This rock is high in silica content and has a high viscosity and polymerization degree. This rock mostly occurs in dark black color, however dark green and brown shades are also commonly seen. It is mostly seen in dark color because it is rich in magnesium and iron. Due to the oxidation state of iron, we get to see the green color.  

NATURAL GEMSTONES ARE UNIQUE AND THEREFORE MAY VARY FROM EACH OTHER AND FROM THE PICTURE.
