icatum
Icatum is a rare and enigmatic mineral discovered in the late 20th century. It is primarily found in the remote regions of the Democratic Republic of the Congo and is known for its unique physical and chemical properties. Icatum is a silicate mineral, belonging to the pyroxene group, and is characterized by its vibrant, iridescent colors that range from deep blues to purples and greens. These colors are a result of its complex crystal structure, which includes layers of sodium, calcium, and magnesium ions.
The mineral was first identified in 1985 by a team of geologists from the University of Kinshasa.
Icatum's chemical composition is (Na,Ca)MgSi2O6, which indicates its membership in the pyroxene group. The mineral is
