Iceland Spar Stone
Also called optical calcite, 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. Use it to remove fear and help you 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. This price is for one Iceland spar, and they are each one to one and a half inches across.
It helps relieve migraines and eye troubles. When used with other crystals, it will often double the healing effects that they have. It can amplify intent like quartz, and can similarly be 'programmed' for a specific purpose.
