Clear Quartz Clusters

The most popular and widely used crystal, this stone is used for amplification of whatever energy is programmed into it, or around it. Clear Quartz is also called "Rock Crystal".  The word crystal comes from the Greek word "krystallos", meaning "ice" (insight into the slang of calling crystals "ice"). This is a good stone for the Crown Chakra, and make lovely prisms when placed in a window.
