About Australian Bronzite Crystal Tumbles
Bronzite crystals are related to the Base Chakra and are another grounding crystal. This crystal is said to help overcome indecisiveness and not believing in yourself. In addition, Bronzite can help you to remain calm in situations where you feel powerless.
In The Crystal Bible 2, Judy Hall states "Spiritually, this is the perfect stone if you have difficulty in stilling yourself, since it brings total serenity".
