About Aura Coated Crystals
"Aura" coatings are fine metallic coating which have been vapor deposited on the crystal at a high temperature in a vacuum chamber by electrostatic charge.
Some of the metals known to be used in the aura process are gold, silver, platinum and titanum.
Aura coatings are permanent iridescent coatings which mimic some of the rare natural iridescent coatings on stones.
