Much like a black hole, Jet once had life and is the product of fossilized wood immersed in water for millions of years. A fun fact about Jet is that when burned or touched with a hot implement, it will exude the smell of coal. Not that we recommend damaging the Jet in your collection or project. Jet is known in the metaphysical world as a protection stone. The darkness inside this gemstone is said to protect the wearer from evil, fear, and violence. Jet is found in England and Spain.
