It is a type of natural glass formed by a large meteoritic impact — similar to moldavites or Libyan desert glass.\nFormation\nVietnamites 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 that it may be located in Cambodia or Vietnam — perhaps near Tonlé Sap Lake.\nCharacteristics\nVietnamite is primarily 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 typical erosion marks of tektites that have passed through the atmosphere at high speed and temperature.\nCollector's value\nUnlike other Indochinese tektites, Vietnamites 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.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028693193029,"sku":"VI019","price":29.38,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/6768-3_vietnamite---25-3g---huyen-song-hinh---phu-yen--vietnam.jpg?v=1779384881","url":"https:\/\/moldavite.it\/en\/products\/vietnamite-253g-huyen-song-hinh-phu-yen-vietnam-vi019","provider":"Moldavite.it","version":"1.0","type":"link"}
