Crystals and gemstones have unique healing properties – that is now a fact, which has been known for the better part of the last few millennia. But how do they work, exactly? Nowadays, we understand that everything in the universe is a form of energy, with a carefully designated frequency and vibration. Nikola Tesla was one of the first who formulated this concept as the key to understanding the universe – and to understanding how some materials interact with each other. This is why crystals are still used today to heal and align bodily cells, chakras or energies. Essentially, a crystal vibrates with its own frequency, but it does so in our own energy field. Through the laws of resonance, it creates a larger field, affecting our nervous system and transmitting its unique properties to our brain and body.
