The metal bead has triggered crystallisation in the glass, with characteristic olivine (forsterite) crystals. The smooth surface shows no sign of terrestrial weathering, so this little rock is fresh from Space. An iconic treasure from Space.
The sensational feature on this micrometeorite is the blue oxidation on the surface. Oxidation and Newton rings are quite common on micrometeorites, but I have never seen anything like this blue one. Even through the glass, seen from the opposite side, the blue oxidation is jaw-dropping, see the little photo.
PROVENANCE: The catalogue number refers to the NMM archive, the index of Jon Larsen’s Project Stardust collection, which is the reference collection for urban micrometeorites. The stone was found, curated, and selected by Larsen. It is in pristine condition, fresh from Space.
