Tumbled Tektite- Assorted

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.

Please note, the price is per tumbled tektite. The images show some of the specimens available. You will receive just one tektite which will be selected at random. 

The size of each tektite varies in measurement, however each measures on average between 2.5-3.5cm, and weighs approximately 12-16g.
