Petzite is a rare silver-gold mineral that is often found in deposits that are rich in tellurium. However, like many mineral names, there are several synonyms that can be used to describe this mineral. Some of the alternative names for Petzite include silver telluride, gold telluride, and argyrodite. Additionally, some experts may refer to this mineral as Hessite or Sylvanite, which are other telluride minerals that are often found in association with Petzite. While these names may be used interchangeably, it is important to note that there may be slight variations in the mineral's chemical composition or physical appearance depending on which synonym is used.
