Fulgurites

Fulgurites are natural glass tubes formed when lightning strikes sand, soil, or rock, fusing the material instantly along the path of the electrical discharge. Temperatures at the strike point can exceed 1,800°C, hot enough to melt silica into glass in a fraction of a second, leaving behind a hollow, often branching structure that traces the exact path the current took underground. No two ever form quite the same way, making each one a unique, one-off record of a single, violent moment of atmospheric electricity.

Our fulgurite specimens are sourced from some of the most productive fulgurite-forming regions in the world, including the sand deserts of North Africa, where large exposed dune fields and frequent powerful desert thunderstorms combine to produce some of the largest and most elaborately branched fulgurites found anywhere. Specimens here range from small representative fragments through larger branching pieces, offering something for collectors at every level, whether you're adding your first fulgurite to a collection focused on unusual natural formations or looking for a striking display piece.
