In emotional life, it allows one to look at the bright side of difficult issues. In healing, it instills life force and aids in rebuilding depleted energy reserves. Green Aventurine can be a stone of “ good luck” and is recommended for those who wish to manifest greater prosperity. It can assist in other situations where one’s overt external actions do not control the outcome. It would be a good stone to carry to the racetrack, a tax audit or a first date.
