Magic Aura Quartz 💜 the process used to create these– magnetron ionization – occurs in nature as the aurora borealis~*~:*) Resulting brilliant colors and rainbow sheen are due to optical interference created by permanently bonding a careful mix of metals (titanium, bismuth, silicone, zircon, etc) to the surface of naturally formed clear quartz crystals. This is the same optical phenomenon that brightens peacock feathers and creates an oil film on water ✨🌈💎
