Etymology

The name 'potassic-arfvedsonite' is derived from the presence of potassium in its chemical composition. The mineral was not named after a person but rather reflects its chemical characteristics. No specific discovery year is provided in the facts.

How to recognize it

Potassic-arfvedsonite can be identified by its black color and blue streak. It has a monoclinic crystal system and a space group of C2/m. Its hardness is not explicitly stated, but as an amphibole, it is generally between 5 and 6 on the Mohs scale. The mineral is typically dense and has a vitreous to dull luster. It may be confused with other black amphiboles, but its streak and chemical composition can help distinguish it.

Trivia

Potassic-arfvedsonite is notable for its complex chemical formula, which includes both potassium and sodium along with iron in multiple oxidation states.
