Obsidian Sphere - Height: 10.5 11.14- 1430 g - (1)

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

A raw material highly sought after in antiquity for the fabrication of sharp tools (predominantly 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 blades for scalpels.
