Tektites
Tektite is a general term given to rocks/minerals which have formed as a result of meteorites hitting the Earth’s surface thousands of years ago. They are a type of glass but are very different to Obsidians which form as a result of volcanic lava hitting water. There are visual similarities between the two minerals although the Tektites tend to have a bit more of a "knobbly" pebble look and feel. The main way to distinguish between them (WHICH IS NOT RECOMMENED) would be to bring a sample of each to its boiling point. The Obsidian would have bubbles, foam and some other chemicals developing.
Moldavite is a Tektite which currently has only been found in the Czech Republic.
