Synonym of:Acanthite


The name 'argentite' refers to the high-temperature form of silver sulphide, only stable over 177 degrees C. Under this temperature any samples of 'argentite' convert to acanthite.

The name argentite is therefore used (confusingly) by some to describe pseudo-cubic crystals of silver sulphide (acanthite) where the original crystal form of the high-temperature argentite has remained. The correct way to label such specimens is "acanthite, pseudo-cubic."
