1st chakra. light brown to dark brown Tourmaline.  Brown is the color of Mother Earth, and is very comforting, nurturing, fertile, and stable. Use Dravite to convey a feeling of warmth, honesty, and wholesomeness to others.  Dravite will help you to connect with the energies of the Earth.  Become more centered and grounded.  Feel more secure in relationships and in your work place. Most of these are DT formation, used to connect two chakras. I love Dravite, it is one of my new favorite gemstones!
