• DETAILED DESCRIPTION

Vietnamese – a rare tektite from Southeast Asia Vietnamese tektites are among the rarest representatives of Indochinite tektites, originating from the continental part of Southeast Asia. It is a type of natural glass formed by a large meteorite impact — similar to moldavites or Libyan desert glass. Formation Vietnamese tektites 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 approximately 700,000 years. The exact crater has not yet been definitively identified, but scientists speculate that it may be located in Cambodia or Vietnam — possibly near Tonlé Sap Lake. Characteristics Vietnamese tektites are mainly composed of silicon dioxide (SiO₂). They usually have a dark brown to black color with a glossy surface and are 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, Vietnamese tektites are very rarely found, making them highly sought-after collector's specimens. 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.
