Its discovery dates back to the 13th century in the Erzebirge massif, in Western Europe. Its name is said to have as its origin its resemblance to the properties of antimony, belonging to the same group. Bismuth is a rare rock that has a very particular geometric structure. Often lamellar and opaque in appearance, it can be recognized by its shiny metallic luster and its relatively high density. It is also possible to find it in the form of poorly developed crystal aggregates, but always with that very characteristic brilliance. The morphology of bismuth can sometimes make it fragile and brittle. Bismuth is a mineral that is frequently formed along geothermal and hydrothermal veins.
