Apache Tear is a form of Obsidian. Obsidian is a silica-rich, glassy, volcanic rock with a water content of less than one percent. They are native to Mexico and the Southwest USA. In general, Obsidian is grounding and used for protection from negative energies breaking down the barriers that hold one back.
It is said that the dark tears of grief that the Apache women shed along the Trail of Tears solidified into this droplet-shaped stone. As such, the energies of this stone aid in the grieving process, and allow for forgiveness. They are also said to support you in connecting with sacred aspects of the physical realm. They raise one’s level of psychic attunement to better perceive threatening individuals, situations or energies. Used in meditation, Apache Tear can help open the the floodgates of grief, aiding and allowing the cleansing of emotional wounds, and releasing feelings of woundedness & victimization.
