Lava stone was used by American Indians when entering battle for its qualities of strength and clarity. It’s believed to provide strength (physical and mental) when facing difficult situations.

Aventurine (Green) stone is known to protect, activate, and clear the heart chakra. Those with heart problems often turn to the stone’s healing qualities of strength and stability. Green Aventurine not only encourages regeneration, but is also thought to be a stone of comfort and balance.
