Pirssonite

Na2Ca(CO3)2·2H2O
Orthorhombic IMA approved

Pirssonite is a rare hydrous carbonate mineral with the chemical formula sodium calcium carbonate dihydrate. It belongs to the orthorhombic crystal system and is classified under the Strunz system as 5.CB.30. This mineral is typically colorless or white and exhibits a vitreous to pearly luster. It is relatively soft, with a Mohs hardness of approximately 3.5 to 4, and has a low to moderate density. Pirssonite is part of the carbonate mineral group and is notable for its water content, which influences its physical and chemical behavior. It is not commonly found in nature due to its instability under most geological conditions.

Etymology

Pirssonite is named after Louis V. Pirsson, an American mineralogist. The mineral was approved by the International Mineralogical Association (IMA), but no specific discovery date is provided in the facts.

How to recognize it

Pirssonite can be identified by its low hardness, typically between 3.5 and 4 on the Mohs scale. It is colorless or white, with a vitreous to pearly luster. Its streak is white, and it has a low to moderate density. Due to its rarity and softness, it is easily confused with other hydrous carbonates, but its chemical composition and crystal system help distinguish it.
