Description

Great Austria classic, for long time the theory was that first discoveries go back to 1845. But after some archeological excavations in the last years we know that first finds were made about 2000 (!!!) years ago. The vein has a dimension of 0.5 - 1 m in thickness and a confirmed length of 400 m. The estimated length is 1000 m! This vein is provided in the "Maissauer Granit", a part of the Thayapluton. The locality is of highest relevance - the Amethyste from Maissau developed about 280 million years ago, one of the oldest amethyste on earth. Much more older than rock crystals from Alps for example (which are about 8 million years old). The vein belongs to a museum area and it is absolutely impossible to dig there, the only available material are only a few specimen from old finds and collections. A complete sharp crystal in this dimension is exceptional, nearly impossible to aquire. The color looks like porcelain, the faces show amazing texture and the amethyst veins show very strong violet color.
