Formed by the heat and shock of a large meteorite impact roughly fifteen million years ago, moldavite is a natural tektite, a silica-rich glass, colored forest green to olive and often marked by a sculptured, pitted surface created as it flew through the atmosphere. The impact that produced the Nordlinger Ries crater in Bavaria scattered moldavite across the Czech Republic, Austria, and Germany, where it has turned up at archaeological sites, suggesting Neolithic use as a talisman. Amorphous and lacking crystal structure, it measures 5.5 on the Mohs scale. A budget-tier semi-precious stone, moldavite is among the most collected and metaphysically revered gems today.

About Moldavite

Moldavite é um tectite formado pelo impacto de um meteorito há cerca de 15 milhões de anos na região da Baviera, na Alemanha, cujos detritos fundidos caíram na atual República Checa. A sua coloração verde-garrafa a verde-oliva única, superfície texturada e translucidez fazem dela uma das pedras mais reconhecíveis do mundo. Tem sido apreciada desde a pré-história, com a moldavite encontrada com a Vénus de Dolní Věstonice e outros artefactos do Paleolítico. A sua popularidade em cristaloterapia disparou nas últimas décadas. Os depósitos estão quase esgotados, tornando as peças de qualidade cada vez mais raras e valiosas.
