Massive Jet from Asturias, a few areas of the world where the best qualities of this mineraloid are found.
Jet is a mineral. 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.
The mineral includes a label with the name and origin in a 4 cm square cardboard box.
*The price is per unit (a single cardboard box of the four shown in the photo)
Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
