All five stones are a part of the collection found during the sixth season of micrometeorite findings/verification in populated areas (2020). The catalogue number refers to the NMM archive (the main index of Norwegian Micro Meteorites, Jon Larsen’s Project Stardust collection), and the stones were found and curated by Jon Larsen.
The MMs has been confirmed extraterrestrial by SEM/EDS and visual identification by Jon Larsen, and is a verified micrometeorite, hereby confirmed in writing. The stone is sold with a Certificate of Authenticity, incl. classification, and one digital color photo and eight SEM images.
