Some information about aegirine:
Aegirine is a member of the clinopyroxene group of inosilicates. Aegirine is the sodium endmember of the aegirine-augite series. It is also known as acmite, which is a fibrous, green-colored variety.
Aegirine occurs as dark green monoclinic prismatic crystals. It has a glassy luster and perfect cleavage. The Mohs hardness varies from 5 to 6 and the specific gravity is 3.2 to 3.4.
Aegirine helps the body to process and remove toxins, and boosts the immune, metabolic and nervous systems. Especially it supports the liver, spleen and gallbladder. This is a great crystal to generate physical energy and stamina, as well as recovery from illness or injury.
