Enhanced quartz crystals with iridescent, brightly colored surfaces are partly natural and partly man made. The crystals are clear or cloudy quartz that has been treated with atoms of precious metals like gold, silver, platinum, indium, titanium, or copper.
There are different methods of creating enhanced crystals:
A vacuum chamber process where the quartz is heated to a set temperature, then a metal vapor is added to the chamber. The metal atoms fuse to the crystals surface, which gives it an iridescent metallic sheen.
Another process is by using a natural electrostatic charge on the crystal this process is generally done with the titanium molecules.
