This beauty will be a treasure in any collection!
Micrometeorite [NMM 1978] is a large (~0.4 mm) cryptocrystalline (CC) type micrometeorite with beautifully oriented form. It is shiny black with a nickel-iron bead in the front (pushed forward by the inertia during the atmospheric deceleration). The front is a perfect “turtleback” but the rare end is aerodynamically elongated. This stone is the jewel in any collection. The stone was found 2019 0424 on the roof of Alf Bjerckes vei 26, Oslo, Norway. The stone is depicted in the Atlas of Micrometeorites page 76.
