Apache Tear (AKA, Mexican Obsidian, as it is no longer legal to source this stone from the U.S.) comes from a meteorite that exploded in the atmosphere and fell to earth. Its matrix is not volcanic or pumice (hardened volcanic powder). Traditionally it was ground with cactus juices and used to heal organ and flesh wounds from the inside out. Apache Tear/Mexican Obsidian is excellent for piercing deep issues and assists in releasing them. Spiritually the stone aids in the forgiveness of self and others. It works through the root chakra and mentally helps erroneous thinking.
