Tanzanite Aura Faceted Pendulum
Tanzanite aura quartz is the end result of a process which uses intense heat to infuse pure gold and indium to natural quartz from Brazil. The atoms fuse to the crystal's surface, which gives it an iridescent metallic sheen on an indigo coloured crystal.
Beautiful and useful too! Pendulums are used much the same way as applied kinesiology or muscle testing to help determine the answer to a question.
