Herkimer Diamond Quartz is called the "stone of attunement".  It can be metaphysically programmed to attune one to an environment, a situation, a quality, or most anything. It is said to assist with balance on the mental, emotional and physical levels. It can be used effectively to clear and open any chakra.

They are said to enhance dreams and meditation and to activate one's connection to the higher self.
