Nickelskutterudite
Nickelskutterudite is a rare sulfide mineral with the chemical formula (Ni,Co,Fe)As3. It belongs to the cubic crystal system and is classified under the Strunz system as 2.EC.05. This mineral is typically metallic in luster and exhibits a range of dark colors, including black to dark gray. It has a moderate to high density and a hardness that is generally between 5.5 and 6 on the Mohs scale. Nickelskutterudite is part of the sulfide mineral group and is known for its association with arsenic-rich environments.

Overview
Nickelskutterudite is a rare sulfide mineral with the chemical formula (Ni,Co,Fe)As3. It belongs to the cubic crystal system and is classified under the Strunz system as 2.EC.05. This mineral is typically metallic in luster and exhibits a range of dark colors, including black to dark gray. It has a moderate to high density and a hardness that is generally between 5.5 and 6 on the Mohs scale. Nickelskutterudite is part of the sulfide mineral group and is known for its association with arsenic-rich environments.
Etymology
Nickelskutterudite is named after the element nickel, which is a key component of its chemical composition. The mineral was later renamed by the IMA, indicating a change in its nomenclature.
How to recognize it
Nickelskutterudite can be identified by its metallic luster and dark coloration. It has a hardness of 5.5 to 6 on the Mohs scale and a relatively high density. The streak of the mineral is typically dark gray. It may be confused with other metallic sulfides, but its composition and crystal system can help distinguish it.
Trivia
Nickelskutterudite is notable for its cubic crystal system, which is relatively rare among sulfide minerals. It contains a combination of nickel, cobalt, and iron, making it chemically complex. Additionally, it was renamed by the IMA, reflecting changes in mineral classification and nomenclature.
