Copper has been used for centuries due to its healing and energetic properties.
Today, almost all modern-day electronics (including radios, televisions, cell phones, computers, and watches) are made with copper and crystal technology. Copper is known to conduct the energy of crystals, human beings, auras, metals (such as Silver and Gold), and the physical and spiritual worlds.
For these reasons I use real Copper, and I also have Gold and Silver options for custom orders!
