Boleite is a relatively uncommon mineral, and there aren't many synonyms for it. However, one possible synonym might be the term "lead hillite". This term is sometimes used to describe a particular type of boleite that has a high lead content. Another possible synonym could be "blue chloride hydrate". This term refers to the chemical composition of boleite - it is a hydrated copper chloride mineral that is typically blue in color. Other words that might be used to describe boleite include "rare", "beautiful", and "valuable". Despite its scarcity, boleite is highly prized by collectors and scientists alike for its unique properties and striking appearance.
