Massive Jet from Asturias, a few areas of the world where the best qualities of this mineraloid are found.
Jet is a mineraloid. It arose from fossilized wood, from tree trunks of the Araucariaceae family, which "lived" in the Jurassic era. Due to its composition, it is considered a variant of coal.
Currently it is widely used in jewelry.
