Collection of four tektite specimens found in Indochina in the 1950s by Dr. H. H. Nininger, founder of the American Meteorite Laboratory (AML) and the most celebrated figure in meteorite history. Tektites are a natural black glass, formed by the heat and pressure of an ancient meteorite impact. The pieces weigh a combined 77.2 grams, and each carries an original American Meteorite Laboratory collection number notation. The specimens range in size from approximately 14 mm x 16 mm x 12 mm to 60 mm x 43 mm x 10 mm. Also includes a small handwritten note in pencil by Nininger. Accompanied by a certificate of authenticity signed by Geoff Notkin of Aerolite Meteorites Inc. and the TV show Meteorite Men. Noted expert and "Meteorite Man" Geoff Notkin educates us on his adventures worldwide as a meteorite hunter in this podcast.
