3rd and 7th chakras.  This is a crystal that is high in lithium which is used to heal depression, and anxiety, great for those who are bi-polar.  I find this stone to be helpful for those who have a hard time completing tasks or projects, good for you procrastinators!  Amblygonite helps one to maintain a sunny out look on life, encourages one to remain centered when life becomes difficult, over come your fear by strengthening your will!  Some feel that Amblygonite is helpful for those suffering with digestive problems such as heartburn and ulcers.  Learn to relax!  These are beautiful gem pieces, very bright.
