71.90 ct MOLDAVITE CARVING – CZECH REPUBLIC

Carved Moldavite Carved Moldavite represents the ultimate "alchemy" of cosmic origin and human artistry. A member of the Tektite group, it is a species I have always held in high regard for its "extraterrestrial" pedigree—the result of a massive meteorite impact in southern Germany approximately 14.8 million years ago. While raw Moldavite is prized for its "sculpted by fire" aerodynamic pits and ridges, a hand-carved piece of extraordinary craftsmanship is a rare treasure of a dying era. As you rightly noted, the tradition of the Moldavite carver is vanishing because the "huge" specimens required for such work have been depleted from the Bohemian fields. For the specialist, a carved Moldavite is a bridge between the stars and the heritage of Bohemia, offering a deep "bottle-green" translucency that has been refined by the hand of a master. The Heritage & Discovery Historical Significance: Moldavite has been a "stone of the soul" in Central Europe since the Stone Age, where it was used for amulets and tools. In the world of fine minerals, it is celebrated for its unique lechatelierite (natural silica glass) inclusions and its distinctive "Bohemian green" hue. It stands as a symbol of transformation and cosmic connection, bridging the gap between a catastrophic celestial event and the elite world of "high-craft" lapidary art. For those who witnessed the opening of the Iron Curtain in 1989, it also serves as a symbol of freedom and the rediscovery of the hidden treasures of Czechoslovakia. This "last piece" in your collection is not just a mineral; it is a historical witness to the opening of a world and the sunset of a specialized craft. Discovery: The name is derived from the Moldau River (Vltava) in the Czech Republic, where the first specimens were identified. Scientifically, it is a glass-like silica produced by the melting of terrestrial rock during the Ries crater impact. Its discovery provided mineralogists with the first clear look at a "tektite" with gem-grade transparency and color. My own respect for this material grew from observing its unique sculpted texture (besednice), which carvers must navigate with extreme precision to avoid fracturing the delicate glass. Since its identification, it has become the most coveted tektite in the world. Important Mines: The undisputed world capital for the finest "Bohemian" Moldavite is the South Bohemian Region of the Czech Republic, particularly the legendary fields of Besednice, Chlum, and Slavče. These areas produced the large, "gemmy" nodules that allowed master carvers to showcase their skills. For the vault, I prioritize these "old-stock" carved pieces, as the modern yield of the mines is largely limited to small fragments, making substantial carved works an extinct luxury of the Bohemian heritage. Mineralogical Profile Description: Moldavite is a natural glass (Tektite) that lacks a formal crystal system. It sits at a 5.5 to 7 on the Mohs scale, making it similar in hardness to man-made glass but significantly more complex in its internal strain and composition. It is characterized by its vitreous luster and its unmistakable "moss-green" to "forest-green" transparency. One of its most identifying traits is the presence of worm-like inclusions of lechatelierite and tiny gas bubbles, which distinguish it from any imitation. In a carved piece, these internal features create a "liquid" depth that plays with the light as the carving is turned. It has a low refractive index ($n \approx 1.48$ to $1.50$) and a characteristic lightness ($SG \approx 2.3$). Because it is a tektite, it is often found in association with the sands and clays of the Bohemian Basin. When I select a carved piece for the collection, I look for the "fluidity" of the lines and the "glow" of the green through the thinnest parts of the carving, as these highlight the sophisticated, three-dimensional geometry of the master's work. It is a high-vibration "cosmic" mineral that offers a unique, architectural beauty unlike any other glass species. Chemical Formula: SiO₂(+Al₂O₃)
