  • Obsidian is a natural glass that forms from volcanic activity.
  • The gemstone is made of the same minerals as granite, but cools so quickly when exposed to air that the minerals do not have time to crystallize.
  • Some inclusions can be bubbles or crystals, creating a random pattern such as snowflake.
  • It may first have been discovered in Ethiopia by a man named Obsius, from whom its name is derived.
  • Obsidian has been used for tool making since at least 21,000 B.C. and used in jewelry for many centuries.
  • American Indians used it for arrowheads, and the Aztecs used a great deal of obsidian for items such as sacrificial knives and mirrors.
  • Today, obsidian is used for dating; the stone weathers slowly at a uniform rate, and the thickness of the weathered layer is measured microscopically and gauged against known standards to give a date in years.
  • Major sources include Iceland, Italy, the U.S.A. (especially Wyoming and Hawaii), Japan and Java.
