Fulgurite Petrified Lightning Fulgurite, also known as “petrified lightning,” is a natural glass formation created by a lightning strike. Fulgurite is the next best thing to hold a lightning bolt in your hand. These specimens are formed when 3000° intense heat from a lightning bolt fuses sand, soil, or rock into a glass-like material. This is how Fulgurite, or commonly known as a lightning fossil, takes shape. Fulgurites have a hollow, tubular shape and range in colour from light to dark brown. Fulgurite is The Stone of Purification. It carries the energy of lightning which stimulates enlightenment and promotes the experience of Kundalini awakening. It breaks old, unhealthy habits and opens up the senses toward spiritual transformation.
