Tumbled Tektite

Tumbled Tektites: Extra-terrestrial Glass from Meteorite Impacts

Formed in the seconds following a hypervelocity meteorite impact, tektites are a unique form of natural glass. They are ejected from the Earth's crust following a meteorite impact, propelled into the atmosphere before solidifying and falling back to the surface. They are often considered "secondary" meteorites. 

Geological and Chemical Composition

Unlike obsidian, which is volcanic glass, tektites are classified as impact glasses or impactites. Their chemical signature is distinctively different from terrestrial rocks, showing a composition that is an amalgamation of target rock from the impact site and vaporized meteorite material. They are primarily composed of silica (SiO2), with trace amounts of aluminium (Al2O3), iron oxide ($FeO$), and other elements. The intense heat of the impact, exceeding 2,000°C, melted and vitrified the rock, creating the unique, streamlined shapes and surface textures characteristic of these specimens.

The tumbling process, while smoothing the outer surface, does not alter the fundamental internal structure or composition. Each stone offers a direct link to a past extra-terrestrial event, a fossilized moment in geological time that provides invaluable data for planetary science and geochronology.

With their smooth, glassy surface and rich, dark colour, these tumbled Tektites are sold individually. The size of each tektite varies in measurement, however each measures on average between 2.5-3.5cm. Tektites will be chosen at random. 

Key Features:

• Authentic Meteorite Impactite: Each piece is a genuine Tektite, a natural glass formed from the intense heat and pressure of a meteorite strike
• Smooth & Polished Finish: The tumbling process enhances their natural beauty and creates a comfortable, tactile feel
  
• Unique & Individual: No two stones are exactly alike, each carrying its own unique story
