Fulgurites are formed when lightning strikes the ground, fusing and vitrifying mineral grains, such as sand. Peak temperatures within a lightning channel are known to exceed 30,000 K, with sufficient pressure to produce planar deformation features, or "shock lamellae," in SiO2, a kind of polymorphism. This is also known as shocked quartz. There are 5 types of fulgurite, with exogenic describing the droplet formations observed in this specific type.


The metallic luster on this specimen along with the contrast of the two different textures gives this piece an out-of-this-world look! 


Fulgerites are known to be beneficial in manifestation and helping balancing frequencies to their natural state.
