Rainbow Amethyst

Enhancement of amethyst may take a variety of forms. Some enhanced amethyst specimens boast a metallic finish, caused when the stone is plated with a metal. To start, the amethyst is selected, then treated via an electrostatic process whereby the stones are put into a vacuum and charged. Heat is applied. The plating metal of choice is then put into the vacuum and it "clings" to the stone, giving it an entirely unique quality of iridescence or colour. This druze cluster is plated with Titanium.

Interestingly, this process was first created as a way to protect the exterior of the space shuttle during exit and re-entry of the atmosphere. The theory was that the plated metal would add the protective properties of metal without the weight. Unfortunately for the aesthetic of space travel, this hypothesis was quickly disproved. Today, this plating process continues to evolve in conjunction to amethyst and other gemstones as an enhancement method.
