Named after the ancient guy who first wrote about it, Obsius, in Ethiopia, & misnamed Obsidian by Pliny the Elder. Obsidian is cooled lava from a volcano! Lava, or Magma cools rapidly when it reaches the Earth’s surface and the silicon dioxide, SIO₂ doesn’t have time to organize into geometric formation, like a quartz crystal. Instead it becomes amorphous, meaning without structure. It is ƒusually black to dark green, but depending on other mineral inclusions, can be red, brown, gold or blue/purple sheened. Some forms are translucent when light is shone through, and may contain straight banding. Found all over the world, it was prized by the Aztecs & the Mayans, used in jewelry & trade. It has conchoidal fracture, meaning that it breaks fwƒithout any natural plane of separation. This fracture pattern allowed obsidian to be utilized as cutting tools, arrowheads and knives in ancient civilizations.
