• DETAILED DESCRIPTION

Vietmanite – a rare tektite from Southeast Asia Vietmanite is among 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 meteoritic impact — similar to moldavites or Libyan desert glass. Formation Vietmanites were formed by a meteoritic 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 to be around 700,000 years. The exact crater has not yet been definitively identified, but scientists hypothesize it may be located in Cambodia or Vietnam — possibly near Tonlé Sap lake. Characteristics Vietmanite is primarily composed of silicon dioxide (SiO₂). It typically has a dark brown to black color with a shiny surface and is generally opaque. The surface is often smooth or shows erosion marks typical of tektites that have traveled 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 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.
