Aegirine, also known as acmite, is a dark green to black mineral. It is a rare iron-containing silicate, often occurring in association with other pyroxenes like augite and hedenbergite. The name aegirine is derived from the god “Aegir” in Norse mythology, who is associated with the ocean. The mineral aegirine is found in syenites and alkali granites
