Aura Quartz is created by bonding fine metal particles (such as titanium or gold) to the crystals in a vacuum chamber with very high heat. You get the benefits of both the crystal and the metal, making aura crystals highly sought-after. They have a beautiful glow that resembles rainbow colours, and come in many forms. *Please Note: All our organic gemstones and crystals are formed by Mother Earth. Natural “imperfections” such as surface cracks, various defects, and the shedding of some crystals are to be expected. Our products are carefully graded, and if we believe there is an UNNATURAL defect - the item will go under our “Imperfect Collection” clearance category. Please research how to properly “cleanse” and charge your crystals, as some crystals must not get wet, and others will fade in prolonged sunlight. All sales are final.*
