Pyroxmangite is a silicate mineral in the pyroxenes group first discovered in 1913. The name pyroxmangite is named after the mineral group pyroxenes.

Within the metaphysical realm of minerals, Pyroxmangite clears the mind of worry, giving confidence and self-esteem. It relieves pressure in social, family and working life. Pyroxmangite can help to heal insect bite and scarring. It can treat emphysema, autoimmune diseases and stomach ulcers.

Please note that MIROFOSS does not suggest in any way that minerals should be used in place of proper medical and psychological care. This information is provided here as a reference only.

Pyroxmangite is generally used as a lapidary mineral.

Pyroxmangite occurs in metamorphosed ore deposits rich in manganese.

Pyroxmangite can be easily confused with rhodonite; however, pyroxmangite is formed in a high-temperature environment while rhodonite is formed in a low temperature environment. Associated minerals include spessartine, tephroite, alleghanyite, hausmannite, pyrophanite, alabandite, rhodonite and rhodochrosite.
