ANGEL AURA quartz (also known as Opal Aura or Rainbow Aura): is quartz that has been treated with platinum, silver and other trace minerals, resulting in the crystals having a pearlescent white colour with an iridescent finish. This crystal has a sweet, fine and high resonance, which seems to sing in the hand. It carries the Rays of the Divine Feminine and of Cosmic Enlightenment, and is a very "connecting" stone. If you wish to extend or activate your upper chakras, whilst retaining a sense of peace and serenity, then this is an excellent crystal to work with. It also brings in the full spectrum of Light, which can help purify and cleanse any of the energy bodies or centres whilst strengthening purpose and resolve.
