You will receive an engraved selenite charging disk similar to the ones in the photo. These are made to order. They have a Merkaba with Metatron's Cube engraved on one side. Size is approximately 4 inches inches in diameter and 1 inch wide.
Selenite crystals work to help you to bring light down from the higher realms into the physical body, to create personal transformation.
The white or transparent crystals have a strong vibration that may open the crown chakra and the soul star chakra.
This will assist you to contact the Divine Mind and to access the Angelic realm. These are high vibration crystals, that also deliver clarity of mind, by cleansing the aura of negative energy build-up, both within the physical and the etheric body.
