Apache Tear

Apache tears are rounded pebbles of obsidian composed of black or dark-colored natural volcanic glass, usually of rhyolite.

The name "Apache tear" comes from a legend of the Apache tribe: in the 1870s, facing defeat, the outnumbered Apache warriors rode their horses off the mountain to their deaths rather than be killed. The wives and families of the warriors cried when they heard of the tragedy; their tears turned into stone upon hitting the ground.
