Ten selected micrometeorites, Jon Larsen Collection 2 (2020)
Ten selected micrometeorites (from 0.2 to 0.35 millimetres) from Jon Larsen’s collection, mounted on a signed microslide, marked “Collection 2/2020”. The stones are of different types and in perfect condition, fresh from Space. This relatively large collection is unique and contains several rare types and phenomena.

All ten 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 urban Project Stardust collection), and the stones were found and curated by Jon Larsen.
VERIFICATION: 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 stones are sold with a Certificate of Authenticity, incl. classification, and one digital color photo and several SEM images. Note the credit for any of these micrometeorite SEM images: ©Jon Larsen (University of Oslo, UiO), and the color photo: © Jan Braly Kihle/Jon Larsen.
