Herkimer diamonds are not actually diamonds but double-terminated quartz crystals, which means each end has six sides instead of four like most other quartz points do. This gives them their unique look and makes them very special indeed! Herkimer diamonds are said to be the most powerful of all quartz crystals and have distinct and harmonious energy. They are used as a stone for healing, meditation, expansion of awareness, communication with guides and other dimensions. These stones can help to connect your physical reality with your spiritual essence and bring inner peace. The clarity of these crystals will allow you to see deep within yourself as well as into the world around you.
