The Legend of the Apache Tear
"One day a party of Apache Indians was ambushed by an enemy tribe. The Apaches fought bravely but were greatly outnumbered and were driven to the top of a very high mountain. Their arrows were gone, and they could fight no longer. Refusing to be taken captive, they leaped, as one, from the cliffs to the rocks below.
"The Apache women, grief-stricken over the death of their brave warriors, shed torrents of tears. The tears became petrified and turned to stone."
Apache tears are actually small pieces of obsidian or volcanic glass. When held in the palm of your hand, the stone appears to be black. When held to the light, you are able to see through the stone.
