Aura Quartz Druzy Round Sterling Silver Ring; size 6

Aura Quartz is natural quartz enhanced by humans to give it a vibrant iridescent quality.  In a process called Chemical Vapor Deposition, crystals are heated to over 1600^o F in a vacuum chamber with metal vapor.  The metal atoms fuse to the quartz and give it a new finish, with the hue depending on the metal used:  gold, silver, platinum, titanium, cobalt, nickel, niobium, or indium. Metaphysically, this stone facilitates self expression.
