• DETAILED DESCRIPTION

Darwin Glass – natural tektite from Tasmania Darwin Glass is a natural glass formed during a meteorite impact through the melting of original surface rocks at the impact site. The locality of this rare glass covers an area of approximately 410 km² south of Queenstown, on the west coast of Tasmania. It is interesting to note that within the Darwin Crater itself—the source of this glass—its presence is rather rare, and most finds come from the surrounding area. Formation Darwin Glass formed approximately 800,000 years ago during a meteoritic impact that caused extreme heat and pressure. This process melted the surface rocks, which then rapidly solidified, creating a glassy material. Characteristics Darwin Glass typically has a green, olive, or black color, with some specimens being translucent and others opaque. Like other tektites, Darwin Glass contains a high proportion of silicon dioxide (SiO₂) and various mineral inclusions depending on the composition of the original rock. It comes in a variety of shapes and sizes, from small fragments to larger pieces with distinctive forms. Rarity and collector's value Darwin Glass is highly valued by collectors for its rarity and limited presence.
