Detailed sheet
aegirine
Found in 1821 by P.Ström and named “acmite” from the Greek “point, edge” in reference to the typical pointed crystals.
But in 1835 Berzelius named it aegirine after Aegir, the Teutonic god of the sea.
Richer in sodium than augite, it oxydizes itself, pruducing chlorite, one of the main inclusions in quartz.

Historical
healing properties
It would increase the will to fight against external aggressions, both physical and mental. It would promote people returning to their personal values and to the realities surronding them, protecting them from negative influences. It would help in following personal convictions and morality and to do that which is required; it actually provides the strength for one to be true to oneself and strengthen integrity and conviction. This would be the stone of the will power, of the morality.
On the heart chakra aegirine would bring liberty of thought, free will, independence, lucidity. Same as epidote, it is related to the liver and to the gall bladder on which it would act positively.
