These are crystals that are carved into animals, angels and skulls and that I have cleansed and attuned to Reiki so that you will receive Reiki energy through the crystal. Many people believe that carving the crystals into these shapes embues the crystal with extra qualities. Skulls are reputed to be extra powerful for transmitting messages. Spirit, power animals have a lot of specific meanings and energies for each animal and can help you connect to your own inner animal guides. Angels can help increase your connection with your guardian angel and higher frequencies.
