Green Aventurine is balancing and supports the immune system, assisting in general physical healing, and is the foremost green heart stone in use in crystal healing. It is considered so harmonising that it is used in Shen Tao Feng Shui specifically to restore harmony in the home when there has been conflict between the inhabitants. In my experience of using it for this purpose, the cause of the conflict often chooses to remove him- or herself from the situation almost immediately, although in some cases genuine harmony is renewed without major change. Green Aventurine is said to enhance self-esteem. The included mica has a dampening effect on electromagnetic radiation, and it can be worn or placed near computers. Aventurine often contains included pyrite, which aids protection and lifts the spirits.
In the case of Peach or Red Aventurine, the clearing and balancing charateristics focus on the lower chakras, from the Solar Plexus down. It is still harmonising, and adds grounding to the mix, making it surprisingly calm, given its orange colour (usually considered vibrant and energising). It releases and clears old, held energy from the Solar Plexus, especially tension and anger, and treats digestive complaints, such as IBS.
