NMM 2794 Vestby is an unusual, barred olivine (BO) micrometeorite. The approximately 260µm stone consists of one single, large crystal domain. Unlike most BO types, which have multiple crystal domains and are known as polysomatic—with each domain having its own orientation—this one has all crystals aligned in the same orientation. As a result, the usually hidden, rectangular top terminations of the olivine (forsterite) crystals are visible. Adding to its rarity are stunning magnetite “Christmas tree” crystals.

 

PROVENANCE: The catalogue number corresponds with the NMM archive, which catalogues Jon Larsen’s Project Stardust collection and acts as the reference for urban micrometeorites. The stone originates from Jon Larsen’s private collection; it was discovered, curated, and chosen for Treasures from Space by Larsen. It remains in excellent condition.
