Description

Fulgurite with a dark black glassy internal cavity 
Fulgurite - Mineraloid Lechatelierite - Petrified Lightning
With internal glass tube like cavity collected in the Western Sahara Desert

Fulgurites are formed when lightning strikes the ground, fusing and vitrifying mineral grains. The primary SiO2 phase in common tube fulgurites is lechatelierite, an amorphous silica glass. Many fulgurites show some evidence of crystallization: in addition to glasses, many are partially protocrystalline or microcrystalline. Because fulgurites are generally amorphous in structure, fulgurites are classified as mineraloids.
