Apache Tear is much gentler in effect than obsidian, it still brings up negativity but is does it slowly so that it can be transmuted. An apache tear is excellent for absorbing negative energy and for protecting the aura. It comforts grief, provides insight into the source of distress and relieves long held grievances. 
This stone stimulates analytical capabilities and promotes forgiveness. An apache tear will remove self limitations and increase spontaneity.
Apache Tears are strong stones for spiritual grounding and they are also powerful for psychic protection. They will raise your ability to recognise the approach of menacing situations, where you may be at risk.
