Meteorites are bought by a surprisingly wide range of people and institutions, from university research labs and natural history museums to private collectors willing to spend millions on rare specimens. The market spans everything from common stony meteorites selling for about 50 cents per gram to pieces of Mars estimated at $2 million or more at auction. If you’re trying to sell a meteorite or just curious about who’s paying for space rocks, here’s the full picture.
Universities and Research Institutions
Scientific institutions are some of the most consistent meteorite buyers. UCLA’s meteorite collection, one of the largest in the world, traces back to 192 specimens purchased in the early 1960s from the family of an astronomy professor and has grown steadily since. Universities don’t just buy for display. They need physical material to cut, analyze, and sometimes destroy in the process of studying solar system formation, planetary geology, and the chemistry of early Earth.
UCLA regularly provides samples to researchers at Caltech, the University of New Mexico, Washington University in St. Louis, the University of Chicago, and international institutions including the British Museum, plus labs in Germany, Japan, Australia, and France. This network of sharing means a single purchased meteorite can fuel dozens of studies across multiple countries.
Carbonaceous chondrites are especially prized by scientists. These carbon- and water-rich meteorites make up only a few percent of collections but offer a critical window into how the solar system formed. They contain organic compounds and volatile materials that may have helped deliver water to early Earth. Because atmospheric entry generates extreme heat that can destroy these delicate compounds, pristine specimens with well-documented recovery histories command serious scientific interest.
NASA also plays a role, though not through the open market. The agency curates Antarctic meteorites recovered by government-sponsored expeditions under the Antarctic Treaty, which defers territorial claims and encourages cooperative scientific exploration. Japan’s National Institute of Polar Research and the European consortium EUROMET handle their own Antarctic collections.
Private Collectors
The private collector market is where prices get dramatic. Sotheby’s has listed individual specimens with estimates in the millions, including NWA 16788, a Martian meteorite discovered in Niger’s Agadez Region in November 2023. Roughly 70% larger than the next biggest piece of Mars found on Earth, it carried an auction estimate of $2 million to $4 million. Christie’s and other major auction houses run similar natural history sales.
Collectors range from casual hobbyists buying thumbnail-sized fragments online to wealthy individuals building curated collections of rare planetary material. What drives value at the high end is rarity and origin. A piece of the Moon or Mars is exponentially more valuable than a common stony meteorite. Witnessed falls, where people actually saw the meteorite come down, also carry a premium because the recovery circumstances are well documented.
Some collectors focus on aesthetics. Iron meteorites, with their distinctive dark fusion crust and striking internal crystal patterns called Widmanstätten structures, are popular display pieces. Others collect by classification type, trying to acquire one specimen from every major meteorite group.
Professional Dealers and Brokers
Between finders and end buyers sits a global network of professional meteorite dealers. These specialists purchase specimens from hunters in the Sahara, Gobi, and Atacama deserts, as well as from people who find meteorites on private land, then resell to collectors, museums, and researchers. The dealer community is relatively small and reputation-driven. Well-known operations include Aerolite Meteorites (run by Geoff Notkin, known from the TV show “Meteorite Men”), SkyFall Meteorites, and dozens of specialized dealers across the US, UK, Poland, France, Switzerland, and Russia.
Some dealers also offer services like appraisals, consignment sales, and help with classification, essentially acting as full-service brokers for people who find or inherit meteorite collections.
What Meteorites Are Worth
Prices vary enormously by type. Common stony meteorites, called chondrites, sell online for as little as 50 cents per gram, or about $15 per ounce. Iron meteorites typically start around $1.77 per gram ($50 per ounce) and go up from there depending on size, condition, and visual appeal. Lunar and Martian meteorites occupy an entirely different tier, with rare specimens reaching thousands of dollars per gram.
For context on the extreme end: Apollo Moon rocks returned by NASA have been valued at roughly $674,000 per gram, though those aren’t available on the open market. Naturally landed lunar meteorites are far cheaper but still among the most expensive natural materials you can legally buy.
Several factors influence price beyond type. Total known weight matters: if scientists have recovered 500 kilograms of a particular meteorite, individual pieces are less scarce. Aesthetic qualities like regmaglypts (thumbprint-like indentations from atmospheric sculpting), intact fusion crust, and interesting shapes all add value. And provenance, the documented history of who found it, where, and when, is critical to establishing authenticity and commanding top prices.
How to Sell a Meteorite
If you have a meteorite you want to sell, the process depends on whether it’s already classified. Classified meteorites with existing documentation and a listing in the Meteoritical Bulletin (the official registry maintained by the Meteoritical Society) are straightforward. You contact a dealer or list with an auction house, provide your specimen’s weight, photos, classification name, and any provenance records like receipts or specimen cards showing chain of custody.
Unclassified meteorites require more work. Dealers will want the weight in grams, approximate dimensions, and clear photos taken in natural sunlight. You’ll also need to state your asking price per gram upfront. If your meteorite came from a witnessed fall, that’s worth mentioning immediately, as fresh falls with known circumstances are highly desirable. The specimen will then need laboratory analysis and formal classification before it can be listed in the Meteoritical Bulletin and sold at full market value.
Meticulous records matter. Dealers and serious collectors treat provenance the way the art world does. Receipts, specimen cards, photos from the find location, and any supporting documentation all help establish that a specimen is properly represented. Without that paper trail, even a genuine meteorite loses significant value.
Ownership Laws in the US
In the United States, a meteorite found on private land belongs to the landowner. This follows English common law principles, and buried meteorites may even fall under mineral rights. If you find a meteorite on someone else’s property, the legal owner is the person who owns the land, not the person who picked it up.
Meteorites found on federal land are owned by the Department of the Interior, though the Smithsonian Institution may acquire them. Collecting meteorites on federal land without authorization can create legal problems. Other countries have widely varying rules: some nations claim all meteorites as state property, while others follow the same landowner principle as the US.
How to Tell If Your Rock Is Actually a Meteorite
Most rocks people suspect are meteorites turn out to be what collectors call “meteorwrongs.” According to Clemson University’s geology museum, two quick disqualifiers are the presence of quartz (meteorites don’t contain it) and vesicles, the tiny holes left by gas escaping from cooling molten rock. Vesicles are common in volcanic rocks like basalt but never appear in meteorites.
The most frequent meteorwrongs are industrial slag (also called cinder or runoff), which is riddled with vesicles, and the minerals magnetite and hematite, which attract magnets and fool people into thinking they’ve found an iron meteorite. Dark black rocks like basalt also get submitted regularly. Real meteorites typically have a thin fusion crust, are denser than ordinary rocks of the same size, and often attract a strong magnet due to their iron-nickel content. If your rock passes those basic tests, a university geology department or professional dealer can help with further identification.
