About Aura Quartz:
 
Aura Quartz crystals provide a calm, relaxing effect on the emotional body and are soothing and healing to the aura. They are exceptional for releasing negativity and stress, old wounds, and long-held doubts about one's self-worth. These crystals are uplifting to the spirit and promote natural joy, hope and optimism. They also embody the properties of the underlining crystal.
This colour effect is not natural. The quartz is heated to 871 °C and then gold vapor is added to the chamber. The gold atoms fuse to the crystal's surface, which gives the crystal an iridescent metallic sheen.
