Description

The image displays several dark olive-green to brownish-green moldavite specimens, characterized by their irregular, often deeply sculpted and pitted surfaces, typical of tektites.

Geological Context

Moldavite is a type of tektite, formed from terrestrial rock melted by the impact of a large meteorite approximately 14.7 million years ago, then ejected into the atmosphere and solidified into glass upon re-entry.
