Key
Key crystals are recognised by having a (usually) six-sided indentation going into a side or face of the crystal. This indentation should ideally end within the crystal in a clear impression of a termination, showing where another crystal once penetrated into the main one and then at some stage was removed. Perfect key crystals are quite rare. As the name suggests this crystal may be used to unlock "doors"; to help provide answers; to help in accessing something that is hidden or lost (not necessarily on the physical plane); or for problem solving of all types. Key crystals are also good to use in meditation and for personal development, especially when working on life-path and directional issues.
