Barred olivine beauty!
Micrometeorite [NMM 3918] is a barred olivine (BO) type with a hole in the front, probably from an escaped metal bead. Radiating out from the hole is one of the strangest crystallisations I’ve ever seen on a barred olivine stone. Apparently, these are the large flat side faces of the olivine plate crystals. They form an unusual pattern that can easily be taken for a porphyritic type. Which it is not.
The variation of the micrometeorites seems endless, and I have not seen anything quite like this one before. A real treasure in any collection.
The stone was found October 12, 2022, at Ullensaker, Viken, Norway.
