Erythrin mass. Its name comes from the Greek "erithros" which means red. It is also called cobalt flower.
Chemically it is a hydrated cobalt arsenate, which always occurs as small acicular crystals of a very characteristic carmine red color.
Its use is limited to collecting and as cobalt ore.
The mineral includes a label with the name and origin and is attached to a 4 cm square cardboard box.

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.
