This is a great specimen, a full 3 inches long with an open see through tube.

Fulgurites are natural tubes or crusts of glass formed from a lightning strike. Their shape mimics the path of the lightning bolt. They have been found worldwide but are relatively rare. Sand fulgurites are the most common and are generally found in beach or desert regions. The strike forms a glass tube where the lightning passes through the middle of the melted material. This tube creates the power of these

high vibration formations. Their energy creates a powerful flow from the heart chakra up, but particularly within the throat and third eye. Good for manifesting your desires when combined with the power of prayer.
