Enjoy beautiful colour and higher energy of tanzanite aura with our tanzanite aura quartz crystals. Tanzanite aura quartz is formed by bonding natural quartz with an infusion of gold, nobium and the rare element indium. This gives it a lovely indigo colour and permanently alters its metaphysical properties. The resulting crystal is ideal for display, spiritual development or healing work. We also have an excellent range of healing crystals with a great choice of crystal varieties.
