Also called optical calcite and Viking Sunstone, this stone was once used by Vikings to get their bearings while on ocean voyages. It activates ALL of the chakras, and brings crystal clarity to the user. It has a very high vibration. You can use it while meditating or doing a simple ritual to help remove fear and therefore focus only on the positive things you want to bring into your life. Because it's so great at this, this stone is a wonderful one for those learning about the law of attraction.
