Aventurine is the foremost stone of prosperity

This stone promotes love, compassion and empathy, while soothing away anger and tension.  It is said this stone gives an all over feeling of well-being.  It is reputed to strengthen the heart, and gives the determination and perseverance to keep going long after you want to stop.  Aventurine is also a powerful luck stone, no matter the color, though green is said to be the strongest in this regards.  It instills in its bearer a sense of positivity and strengthens the sense of self. Aventurine can also guard against electromagnetic energy and helps protect against environmental pollution.  It is said that taping a piece to your cell phone can protect against the cellular emissions.  It takes the “pollutants” out of your thoughts as well, quieting the mind and allowing for solid grounding.
