Andesine

"This gemstone is believed to hold certain powers of mystery, as was called the “light-bringer”. It is said to lift ones conscious and connect him to the activities of the universe. Andesine Labradorite is said to block unwanted actions caused by another’s aura and stop energy from leaking, creating a protective cycle against negative energy which leaves the body so as to not allow re-entry.
On a psychological level it is said to mitigate fear and insecurity whilst also providing with a hyperactive mind and imagination, in addition to bringing new ideas and help with meditation.
This specific gemstone is also said to cure diseases surrounding the eyes and brain, while also relieving one from stress and setting the metabolism; it may also be used as a “witness” in radionic treatment.
It is best used above the higher heart chakra, or held in ones palm when considered to be in need from the owner."
