Obsidian is a naturally formed glass produced by volcanoes when the lava, which was rich in silica, had rapidly cooled. It is known as a stone for protection & cleansing and is thought to help release negative energy in your body as well as your energetic field (or aura.) Obsidian is also used by energy healers for getting in touch with buried issue. In the Aztec culture, it is called Itztli or the divine stone & is under the power of the god Tezcatlipoca or Smoking Mirror.
