Collectible minerals - full range in stock "Goethite"

Goethite is a mineral that has another name - “needle iron ore”. Already from the name it is clear that it is an iron-containing mineral. It is formed from a number of other iron-bearing minerals and is the end product of their weathering. Goethite is named after the great German poet Johann Wolfgang von Goethe, who was not only a poet, but also a naturalist and a collector of minerals. This mineral has a very wide distribution. Its forms are diverse: from crusts to crystals. In addition, it forms very spectacular pseudostalactites.
