It is a type of natural glass formed from a large meteorite impact — similar to moldavites or Libyan Desert Glass.\nFormation\nVietnamese tektites were formed from 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 to be around 700,000 years old. 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\nVietnamese tektite is mainly composed of silicon dioxide (SiO₂). It usually has a dark brown to black color with a lustrous surface and is 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.\nCollector's value\nUnlike other Indochinese tektites, Vietnamese tektites 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":58028006932805,"sku":"VI055","price":22.63,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/36998-4_vietnamite---18g---huyen-song-hinh---phu-yen--vietnam.jpg?v=1779379082","url":"https:\/\/moldavite.it\/en\/products\/vietnamite-18g-huyen-song-hinh-phu-yen-vietnam-vi055","provider":"Moldavite.it","version":"1.0","type":"link"}
