Obsidian Sphere - Height: 9.8 11.14- 1480 g - (1)

Obsidian is a volcanic glass whose formation is due to the very rapid cooling of lava, always rich in silicate ions. Obsidian is a natural glass, entirely similar to that of human-made glass.

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