Moldavite

18 in the gallery

Moldavite is a natural silica glass formed by a meteoritic impact that melted surrounding rocks and rapidly cooled to glass. It typically appears in olive to deep green hues, with a glassy luster and an irregular, nodular habit that reflects its explosive origin. As part of the tektite group, Moldavite often displays a smooth to conchoidal fracture and a translucent to translucent-green appearance that can vary across specimens.

About Moldavite

Notable specimens come from central European sites linked to the impact event, particularly in the Czech Republic, with related finds reported in nearby regions of Germany and Slovakia. Localities within and around ancient impact structures contribute to the variety and character of pieces seen on the market, including sometimes pitted or etched surfaces due to weathering.

Collectors value Moldavite for its origin story, distinctive coloration, and the sense of dramatic provenance it carries. Pieces range from small chips to larger, more dramatic fragments that reveal the glassy texture and occasional flow lines. Its rarity in pristine, well-preserved forms and its association with one of geology’s most famous impact phenomena continually draws interest from mineral lovers and collectors alike.
