What makes crystals so special? Did you know they are the only stone that can hold a frequency or vibration. This means they can hold information. That's why they use clear quartz in computers, watches and other devices. When people hold or touch crystals they leave impressions on them which is why they need cleansing. They all have their own particular vibration and frequency, which comes from their molecular composition. From the way they move and interact, these vibrations and energies work in benefiting and uplifting our mood, mind, and health in a considerable manner, often in the way essential oils and aromatherapy work.
