It is a type of natural glass formed by a large meteorite impact—similar to moldavites or Libyan desert glass.\nFormation\nVietnamites 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 hypothesize that it may be located in Cambodia or Vietnam—possibly near Tonlé Sap Lake.\nCharacteristics\nVietnamite 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 passed through the atmosphere at high speed and temperature.\nCollector's value\nUnlike other Indochinite tektites, Vietnamites 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.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028692898117,"sku":"VI068","price":22.86,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/37526-5_vietnamite---15-3g---huyen-song-hinh---phu-yen--vietnam.jpg?v=1779384875","url":"https:\/\/moldavite.it\/en\/products\/vietnamite-153g-huyen-song-hinh-phu-yen-vietnam-vi068","provider":"Moldavite.it","version":"1.0","type":"link"}
