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
モルダバイトは、約1500万年前に中央ヨーロッパのネルドリンゲン隕石衝突によって形成されたガラス状の天然衝突ガラス（テクタイト）で、深い森のような瓶緑色が特徴です。主にチェコ南ボヘミアのモルダウ川流域で産出し、希少性・特異な起源・宝石としての美しさが相まって世界中のコレクターや水晶・鉱物愛好家に非常に高い人気を誇ります。表面の特徴的な流状・気泡状のスカルプチャーがモルダバイトの証明となります。
