The Herkimer Diamond is a high quality clear quartz that is only found in Herkimer County, New York. The crystals grow in the unique shapes you see, and they are found with all the natural facets, often with two pointed ends (these are not cut/polished/faceted). The energy of a herkimer is a very high vibration, and assists with clearing your energy, manifesting and deep healing work. It works well with all the chakras, and is most often used with the Crown and Third Eye Chakras, for connecting you with your higher-self and intuition. Herkimer Diamonds are great for attunement, intention setting, accelerating your journey, and for "dream work".
Just as Quartz can amplify the energies/qualities of other crystals, Herkimer Diamonds do this as well. Lower vibrating crystals can become more potent when paired with a Herkimer Diamond. They are also used for meditating or programing with an intention, to help amplify intentions and accelerating the process. I personally love using Herkimers in crystal grids, to amplify the surrounding crystals and crystal grid intention.
It's a great way to get a sparkly, high-vibration crystal, at a very affordable price!
