Tektites are chunks of glassy material found in a number of locations across the globe. Most are blackish in colour and show signs of exposure to intense heat. The exceptions to this are the beautiful (and rare!) Moldavites from Eastern Europe, the yellowish Libyan glassites and the green-grey Darwinites. Moldavites are often an exquisite emerald green colour, and are frequently used in jewellery making.
There has been much controversy about the origins of tektites: their appearance and distribution in ‘strewn fields’ suggests a meteoric origin, but their chemical composition is very close to that of terrestrial rock types.
Many geologists believe that most tektites were created when massive impacts hurled molten surface rocks high into the atmosphere: remelting on re-entry produced the characteristic shapes and evidence of ablative heating. Other types may have been formed in situ by the extreme energies of a meteoric impact.
However, recent research by former NASA astronomer Dr. John A. O’Keefe suggests that Tektites may have had their origin in lunar volcanoes or impacts, and that they may once have orbited the Earth as a Saturn-like ring.
ACTUAL AS SEEN: The image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions so this listing will change after you purchase. The scale cube in the photo is 1cm to give a visual size.
