TEKTITE - impact of METEORITE - 800,000 years!!! Polished. - 38 g

Tektites (from the Greek tektos, melted) are natural glassy objects formed by the impact of large meteorites on the Earth's surface. Tektites are the driest minerals known, with an average water content of 0.005%. This is very rare, since most of the craters where tektites formed were underwater before the impact. It has also been discovered partially fused zircon within some tektites. This, along with the water content, suggests that tektites formed at very high temperatures and pressures (similar to those required to form diamond). Indochinites, like the one in this lot, formed by the impact of a large meteorite about 800,000 years ago, in what is today Laos, according to the most recent studies. The shock was brutal, so that molten material covered 10% of the Earth's surface, with indochinites even found in Antarctica. The specimen in this lot is of good size, nicely shaped, and perfectly polished. Do not miss this opportunity! We are members of the leading international associations related to meteorites, so we guarantee for life the authenticity of all our meteorites and jewelry made from this material. Buy with confidence. - IMCA members with number #7412 (International Meteorite Collectors Association) - GMA members with number #G0095 (Global Meteorite Association) - The Meteoritical Society members with number #6667 Best regards and good luck!
