Description
Obsidian – Green Tumbled Stone
Like all Obsidian, the Green variety has an amorphous crystal system and is in the mineral class of oxides. It is formed volcanically when lava that was rich in silicic acids cooled very quickly. The result of this creates a mass that is very rich in minerals, and sometimes gas inclusions.
Its coloring ranges from a deep green to a paler aqua/bluish/green shade. This variety has come from Pachuca, Mexico and is identified by its unique green color and its internal purity (quite noticeable when held up to the light). Variations in the oxidation state of the small amounts of iron contained in its mix provides its greenish hue.
