5th and 6th chakra. Light Blue is the color of the 5th chakra, or throat center. Indigo is the color of the 6th chakra or third eye. I like to think of this mineral as one of creative expression and communication. Chrysocolla is an important stone for it releases grief, sadness, and fear from the throat chakra. Brings joy, certainty, and peace. Supports letting go of pain and worry.  Azurite is wonderful for learning how to open the third eye. Excellent color!
