Crystals are mineral deposits that form under immense pressure over millions of years, giving them precise atomic structures. Historically, royalty and religious figures used crystals for their symbolic and therapeutic properties. Modern science shows that crystals have vibrational energy properties and can be used to absorb, amplify, and radiate electromagnetic signals. Quantum physics also demonstrates that all matter is condensed vibrational energy. Crystals can thus be viewed as energy stores that vibrate at precise frequencies, and which may be able to transfer healing energy to the human energy field through sympathetic resonance.
