• DETAILED DESCRIPTION

Vietnamese – a rare tektite from Southeast Asia Vietnamese tektites belong to the rarest representatives of Indochinese tektites, originating from the continental part of Southeast Asia. It is a type of natural glass formed by a large meteoritic impact – similar to moldavites or Libyan Desert Glass. Formation Vietnamese tektites 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 speculate it might be located in Cambodia or Vietnam — possibly near Tonlé Sap lake. Characteristics Vietnamese tektite is mainly composed of silicon dioxide (SiO₂). It usually has a dark brown to black color with a glossy surface and is generally opaque. The surface is often smooth or shows erosion marks typical of tektites that have passed through the atmosphere at high speed and temperature. Collector's Value Unlike other Indochinese tektites, Vietnamese tektites are found very rarely, 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.
