Sourcing Meteorites: A Collector’s Guide

Meteorites are among the most extraordinary natural objects on Earth. Each one is a fragment of another world—whether an asteroid, the Moon, or even Mars—that has traveled through space before landing here. For collectors, museums, and enthusiasts, sourcing meteorites responsibly and authentically is essential. This guide explores where meteorites come from, how they reach the marketplace, and what to consider when sourcing them.

Where Do Meteorites Come From?

Meteorites are found all over the world, but certain regions are particularly rich in discoveries:

• The Sahara Desert – The dry climate preserves meteorites well, and many notable finds come from Northwest Africa (NWA). These meteorites are often classified and numbered by institutions once studied.

• Antarctica – Glacial movements and stark landscapes make dark meteorites stand out against the ice. Scientific expeditions recover them, though these finds are reserved for research, not private sale.

• American Southwest – Locations like Arizona, Texas, and New Mexico have long histories of meteorite hunting, with notable finds like the Canyon Diablo fragments near Meteor Crater.

• Argentina & Chile – Large iron meteorites, such as Campo del Cielo specimens, are often recovered from these regions.

How Meteorites Reach Collectors

Most meteorites in private collections are discovered by professional hunters, nomads, or local residents in desert regions. They are then:

1. Verified – Samples are sent to laboratories or institutions to be studied and classified.

2. Certified – Classification reports are published and specimens given official names or designations (e.g., “NWA 869”).

3. Distributed – Meteorites are sold to dealers, auction houses, or directly to collectors.

Ensuring Authenticity

The market for meteorites is vibrant, but not without risk. Fake or misidentified specimens do exist. To avoid problems:

• Buy from reputable dealers – Look for sellers affiliated with organizations like the International Meteorite Collectors Association (IMCA).

• Check documentation – Authentic specimens often come with classification paperwork, find location, and provenance.

• Learn the basics – Genuine meteorites often have distinguishing features like fusion crust, regmaglypts (thumbprint-like indentations), or Widmanstätten patterns in iron types.

Ethical Considerations

Meteorite sourcing also raises ethical questions. Some points to consider:

• Legal restrictions – In some countries, meteorites are protected by law and cannot be exported or sold. Always ensure specimens were obtained legally.

• Community respect – In desert regions, meteorites are often first found by locals. Supporting fair trade practices ensures communities benefit from their natural resources.

• Conservation vs. collection – While private collections play a role in preservation and study, some meteorites may be better kept in museums for public access and research.

Tips for Aspiring Collectors

• Start small with affordable specimens like NWA chondrites or Campo del Cielo irons.

• Join collector groups or forums such as Meteorite Mailing List to learn from experienced enthusiasts.

• Educate yourself on classification systems, handling, and preservation (iron meteorites in particular need care to prevent rusting).

Conclusion

Sourcing meteorites is about more than simply owning a piece of space—it’s about participating in a community that values science, history, and the wonders of the cosmos. By sourcing responsibly, ensuring authenticity, and respecting both the law and local communities, collectors can help preserve these cosmic treasures for future generations.
