Ever looked up at the moon and wondered what it would feel like to actually hold a piece of it? Most of us have. But then the logic kicks in. You start thinking about the logistics, the rocket fuel, and, inevitably, the price tag. Honestly, if you’re looking to buy an authentic piece of the lunar surface, you’re looking at a market that is part high-stakes auction, part legal minefield, and part "finders keepers."
So, how much does a moon rock cost? If we’re talking about the rocks brought back by NASA astronauts, the answer is basically "everything you own and a prison sentence." But if you’re willing to settle for a lunar meteorite—a rock the moon threw at us—the price becomes a lot more down-to-earth.
The $51,000 Per Gram Government Estimate
NASA doesn't really "price" its moon rocks because they aren't for sale. They are considered national treasures. However, when things get stolen, the government has to put a dollar sign on them for court proceedings.
Back in the early 2000s, an intern named Thad Roberts managed to steal a safe full of lunar samples from the Johnson Space Center. He didn't just want to look at them; he allegedly wanted to have sex on them (yes, really). When the FBI caught him, they valued the 17 pounds of material he took at roughly $21 million.
If you do the math, that’s about $2,700 per gram in 2002 dollars. Adjusted for the inflation we're seeing in 2026, and considering the sheer rarity, experts often cite a "replacement cost" of over $50,000 per gram for Apollo-era material.
Why Apollo Rocks are Different
- Provenance: These were hand-picked by humans.
- Documentation: Every speck has a "birth certificate" detailing exactly where it was found in the Sea of Tranquility or the lunar highlands.
- Legal Status: It is illegal for a private citizen to own Apollo lunar samples. Period. If you find one at a garage sale, call a lawyer before you call a collector.
The Loophole: Soviet Luna Samples
There is one very specific exception to the "illegal to own" rule. In 1970, the Soviet Union’s Luna-16 robotic probe returned to Earth with a tiny amount of soil. The Soviet government gifted three tiny pebbles from this haul to Nina Ivanovna Koroleva, the widow of their lead rocket designer.
Because these were a legal gift from a sovereign nation to a private individual, they became the only "documented" moon rocks that can be legally traded on the open market.
In 1993, these three pebbles sold at Sotheby’s for $442,500. Fast forward to late 2018, and they went back under the hammer, fetching $855,000. These things are smaller than a grain of rice. We are talking about a valuation of roughly $4.2 million per gram. That makes them significantly more expensive than diamonds, gold, or even California real estate.

Lunar Meteorites: The Affordable Moon
If you don’t have a million dollars sitting around, don’t worry. You can still own a moon rock. You just have to buy one that fell out of the sky.
When an asteroid hits the moon, it kicks up debris. Some of that debris escapes the moon’s gravity, wanders through space for a few million years, and eventually crashes into Earth. These are called lunar meteorites.
Since NASA didn't go get them, the government doesn't own them. They belong to whoever finds them, usually in the Sahara Desert or Antarctica.
Current Market Rates for Meteorites
Right now, in 2026, you can find small slices of lunar meteorites for surprisingly reasonable prices.
- Dust and Tiny Fragments: You can get a "display" containing a few milligrams of moon dust for about $25 to $50. It’s tiny, sure, but it’s the moon.
- Small Slices (0.1g to 0.5g): These usually go for $100 to $300.
- High-Quality Specimens: If you want a chunky piece that actually looks like a rock, you’re looking at $500 to $1,000 per gram.
Prices fluctuate based on the "type" of rock. A piece of the lunar highlands (the bright parts of the moon) might cost more than a piece of lunar basalt (the dark "seas") depending on what’s currently available on the market.
Spotting the Fakes
Because the price of moon rocks is so high, the market is flooded with fakes. Honestly, if you see a "moon rock" on eBay for $10 that looks like a piece of charcoal, it probably is.

Real lunar meteorites are verified by labs like the University of Washington or UCLA. They look for specific ratios of isotopes and minerals like anorthosite that are rare on Earth but common on the lunar surface. Always ask for a Certificate of Authenticity (COA) from a member of the International Meteorite Collectors Association (IMCA). If the seller isn't a member, walk away.
Is it a Good Investment?
Valuing space rocks is tricky. Unlike gold, which has a global "spot price," moon rocks are worth whatever the richest person in the room is willing to pay.
Over the last decade, prices for lunar meteorites have actually stabilized because we've found more of them. However, "flown" material—stuff that was actually on a mission—only goes up. As private companies like SpaceX and Blue Origin start their own lunar missions, the "rarity" of the moon might change. But for now, an Apollo-era grain of dust remains one of the most valuable substances on the planet.
Your Next Steps for Owning a Piece of the Moon
If you're serious about getting your hands on some lunar material, skip the shady listings and go straight to reputable dealers like Aerolite Meteorites or FossilEra. Start with a small "lunar box" display; they usually cost under $100 and come with a guarantee. If you're a high-end collector, keep an eye on the "Space Exploration" auctions at Sotheby's or Christie's, but be prepared to verify the provenance with a fine-toothed comb—and have your bank account ready for a six-figure hit.
