Obsidian - Apache Tears

is not a mineral but volcanic glass formed as an extrusiv igneous rock. Obsidian is a mixture of amorphouse or cryptocrystalline grains of silica minerals formed as a result of quickly cooled lava. Petrograficaly belong the obsidian to the rhyolit-dacit family.

Apache Tears:

During the final eruptive phase, there was an extrusion of viscous lava consisting of practically pure silica. Due to rapid cooling, this lava solidified into volcanic glass - obsidian. Due to chemical and physical processes, most of the obsidian was transformed into perlite, in which the inclusions of the original obsidian were preserved in the form of spherical nodules. The term "Tears of the Apaches" originated after 1870, when the United States Army suppressed the Apaches in the Arizona Territory. Although it is a rock, Apache tears are a popular exhibit in mineralogical collections.
