Obsidian – Golden Sheen Tumbled Stone

Like all Obsidian, the Golden Sheen 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 is generally a black or deep brown color that displays a golden chatoyance (cat’s eye effect) when viewed in strong light. This chatoyance is created from gas bubbles aligning across the layers of the gem during its formation.
