Obsidian sphere from Mexico, main mineral obsidian, weight 740 g, diameter 8.9 cm.
Description from the seller
Obsidian is a volcanic glass whose formation is due to the extremely rapid cooling of lava, still rich in silicate ions. Obsidian is a natural glass, entirely similar to the one produced by humans.
A highly sought raw material in antiquity for the manufacture of sharp tools (primarily knives) and was one of the commodities that animated trade in the Mediterranean and sustained the economic life of its mining sites. Today it is still worked into small decorative objects, pendants, scalpel blades.
Splendid sphere of obsidian, originating from Mexico.
