Apache tears are a form of obsidian natural volcanic glass. The legend: In the 1870's the US cavalry had 75 Apache warriors outnumbered and cornered. Rather than being killed by the cavalry they rode their horses off of a cliff to their death. The wives and families went to the cliffside to mourn the brave warriors. Their grief so strong their tears were trapped into the rocks they fell on. Carrying these stones helps with healing sorrow and grief, because they already have tears enough in them for all of us. Wonderful healing stones. They clear negative energy and emotions. The stones are translucent, so light will pass thru them. If you hold them to the light you can see the "tears" inside of them. Sizes vary as shown in photos. Price is for five stones.
