Overview: Healing with crystals
The silicon chips that are used in computers, are encodings of quartz crystal that has been programmed to record, store, and gestate information, in numerical binary 0-1 format. This is the most modern use of raw crystal energies, and is the most powerful crystal energy system that you can buy, simply because electricity runs through the chip and therefore animates it and expresses its metaphysical properties, and the flow of energies.

So too the computer, tablet, iPad, and mobile phone have display screens that are very powerful and can in fact convey healing vibrations for good health, prevention of illness and amplify curative powers.
