Your modern day basic knowledge of science may be against this concept of crystal healing but this technique has been used for thousands of years and has been known to work, and work well. Science doesn’t teach or share this information to most people, therefore most people do not believe these magical crystals are anything other than rocks. The science behind healing crystals is quite amazing.
History of Healing Crystals
Crystal healing dates back at least 6,000 years to the time of the ancient Sumerians of Mesopotamia. Ancient Egyptians are also some of the first people to use these crystals (lapis, lazuli, turquoise, etc). They used these to ward off illness and negative energy. These cultures used these for cosmetic reasons and for therapy/health benefits.
Today the Hindu or Buddhist cultures use the concept of chakras, which are vortices of life-energy. All human life is made up of physical and spiritual elements; if we were just physical then we would just be objects. Every human has their own unique aura, entity and spirit. Our energy is why we are alive, our universe made up of energy.
Science behind Crystal Healing
Crystals are millions of years old, created during the earliest parts of earth’s formation. They have a geometric structure that makes them the most orderly structure that exists in nature, which means they have the lowest amount of entropy. In physics, entropy means a thermodynamic quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
 
A crystal’s structure is unique and responds to the inputs of all the different energies around it, which leads to emitting specific vibratory frequencies. The crystal lattice (the 3-D arrangement of atoms inside) is so balanced and orderly, the energy that discharges is consistent and when unbalanced energy is inputted it is transformed into a harmonic energy.
How Crystal Healing is Done
Crystal healing stones are assigned various properties, this may vary depending on the healer. Topaz may provide mental clarity. Amethyst is beneficial for the intestines for example. Many of the time during a full treatment session, a crystal healer places various crystals on your chakra points. Other times people may use crystals as jewelry (amulets), under their pillow or located in their homes. It is known that these crystals ward off sickness and negative energy or absorb positive energy.
