Obsidian Sphere - Height: 9.8 11.14- 1070 g - (1)

Obsidian is a volcanic glass whose formation results from the very rapid cooling of lava, still rich in silicate ions. Obsidian is a natural glass, completely similar to the human-made one.

A highly sought-after raw material in antiquity for the manufacture of sharp tools (primarily knives), it was one of the commodities that fueled Mediterranean trade and sustained the economic life of the extraction sites. Today it is still worked into small decorative objects, jewelry, and scalpel blades.
