Massive brown Limonite.
Limonite is not a mineral as such but a mixture of several minerals, its main component is Goethite. It is a very common material in oxidized areas with deposits with iron ores. It originates from the decomposition of many iron ores.
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
*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.
