Azurite is very potent in cranking up your pineal gland. The deeper the blue, the stronger the energy that goes into your pineal. Azurite is very similar to Lapis Lazuli. Azurite also comes in other variations such as Azurite with Malachite. In this case, the energy flows to your heart as well as cranking up the pineal.
