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
捷克陨石（绿玻陨石）是一种透明的橄榄绿至深绿色天然玻璃，形成于约1500万年前德国巴伐利亚地区的陨石撞击事件，主要分布于捷克波西米亚南部、摩拉维亚和奥地利。捷克陨石表面常呈现出独特的流纹状、树皮状或气泡状雕刻纹理，是地外星体与地球相遇的珍贵见证。它是玻陨石（tektite）家族中最著名、商业价值最高的成员，深受宝石和矿物收藏爱好者追捧。随着资源日趋枯竭，优质捷克陨石的价格持续攀升。
