Description: This exceptional Darwin Glass example (13.645 grams) has a remarkable combination of features displaying its unique and dynamic formation. The irregular shaped dark brown-black glass is partially translucent and takes the form of twisted masses of glass fragments and has a flowing texture defined by lines of open elongated bubbles, along with numerous partial and complete holes. A choice specimen! Background: Darwin Glass was formed by the catastrophic heat released from an ancient meteorite impact in Tasmania (Australia), believed to have occurred some 800,000 years ago. The meteorite impact is thought to have released an enormous amount of energy, melting and then rapidly cooling the surrounding rock to form this unique glass. Although most of the meteorite was vaporized on impact, this glass is enriched in nickel, cobalt, chromium, magnesium, and iron in the glass fragments, which are components of extraterrestrial material from the meteorite (K.T. Howard, “Geochemical Systematics in Darwin Impact Glass,” 66th Annual Meteoritical Society Meeting 2003).
