Aqua Aura Quartz is highly stimulating to the Throat and Third Eye chakra, enhancing one's ability to communicate inner truth. It also has a calming effect on the emotional body. Aqua Aura Quartz can be used to soothe anger, cool feverishness and release stress. Aqua Aura Quartz is produced when Clear Quartz points or clusters go through a special treatment process in which their surfaces are bonded with vaporized or finely powdered pure gold. The resulting crystals exhibit vivid blue surfaces with subtle flashes of iridescent rainbow colors.
