Archangel Gabriel is of the white ray and is a protector of truth and innocence, and a master of white light. White dragon Seraphim is a dragon angelic order are protectors of the gates of Christ consciousness and of the angels.
Crystals of the white ray are considered to be cleansing and also elevate the frequency of your energy body and expand your consciousness. Associated with the crown chakra and soul star chakras, these can also often work with all chakras at once. Many crystals of the white ray do not absorb energy, rather they transmit energy.
Those interested in metaphysics will often work with these energetically as a white healing ray of light. Of course, crystals of the white ray have many other properties well above and beyond what we are describing here.
