Mimetite
Mimetite is an arsenite mineral, and its name is derived from the Greek word 'mimetes' which means 'imitator', a reference to mimetite's similarity to pyromorphite. Unlike pyromorphite, mimetite is a much less common mineral.
It is used as a talisman to ensure harmony and as a buffer of the effects of the outside world. It brings balance to an area or can be used in healing in conjunction with the heart chakra.
