• DETAILED DESCRIPTION

Vietmanite – a rare tektite from Southeast Asia Vietmanite belongs to the rarest representatives of Indochinite tektites, originating from the continental part of Southeast Asia. It is a type of natural glass formed from a large meteorite impact — similar to moldavites or Libyan desert glass. Formation Vietmanites were formed by a meteorite impact that caused extreme heat and pressure. As a result, the Earth's surface rocks melted and, after rapid cooling, solidified into natural glass. Their age is estimated at about 700,000 years. The exact crater has not yet been definitively identified, but scientists speculate that it may be located in Cambodia or Vietnam — perhaps near Tonlé Sap Lake. Characteristics Vietmanite is mainly composed of silicon dioxide (SiO₂). It usually has a dark brown to black color with a shiny surface and is generally opaque. The surface is often smooth or shows signs of erosion typical of tektites that have passed through the atmosphere at high speed and temperature. Collector's value Unlike other Indochinite tektites, Vietmanites are very rarely found, making them highly sought-after collector's items. Each piece represents an authentic fragment of cosmic history and a unique natural phenomenon formed during one of the most powerful events in Earth's history.
