Are tiny meteorite fragments worth collecting?
Yes. Small fragments and micromounts are affordable, take little space and can represent rare types that would be unaffordable as large specimens.
Many collectors focus on small specimens, and there are good reasons for this.
Affordability. Rare meteorites, such as Martian, lunar or unusual achondrites, can be very expensive in large pieces. Small fragments, weighing less than a gram, make them accessible.
Variety. A collection of small specimens can represent many meteorite types, groups and famous falls, illustrating the diversity of meteorites. Some collectors aim to have an example of every chondrite group or every iron chemical group.
Micromounts. Very small specimens are often displayed in small boxes, sometimes mounted on pins or set in clear plastic, and viewed with a hand lens or microscope. Collectors call them micromounts. They take little storage space.
Historical interest. Small pieces of historic falls, such as L'Aigle, Ensisheim or Wold Cottage, can connect a collection to the history of science.
Considerations. - Small fragments are easy to lose or confuse, so careful labelling is essential. - Make sure the specimen comes with clear identification and provenance, because tiny pieces are harder to verify. - Crusted fragments or ones showing key features, such as chondrules or metal, are more informative. - Some very fragile meteorites, such as CI chondrites, crumble easily even in small pieces.
Scientific value. Small specimens are rarely needed by scientists, but well-documented ones can still be useful, for example for comparison or education.
Collecting small specimens is a great way to learn, since each piece invites research into its type and story.
