Arfvedsonite is a black crystal that was first discovered in 1823 by chemist Johan August Arfwedson in Sweden. Its name comes from Arfwedson’s last name and the Greek word for “stone.”

Arfwedsonite is made up of iron, magnesium, and sodium and is often found in igneous rocks. It has a Mohs hardness of 6 and a specific gravity of 3.7-3.9. Arfvedsonite is not a very popular crystal, but it is known for its ability to help with grounding, protection, and dispel negativity.

Arfvedsonite can be found in many places around the world, including Norway, Canada, Australia, Antarctica, and the United States.
