Fulgurite Raw

1- raw piece of Fulgurite

Fulgurite, also known as "petrified lightning," is a natural glass tube or crust formed when intense lightning strikes sand or soil, fusing the material into a glassy, irregular shape, often with a rough exterior, smooth interior, and branching structure like the lightning bolt itself. Found worldwide in sandy regions like deserts and dunes, these brittle, silica-rich formations are prized by collectors, sometimes costing significantly depending on rarity and size, and provide scientific insights.
