Ever looked up at the moon and wondered if you could actually own a piece of it? You aren't alone. Whether you’re a die-hard space geek or just someone who likes weird, rare collectibles, the question of how much are moon rocks is a rabbit hole that leads to some pretty wild numbers.
Honestly, it’s a bit of a "good news, bad news" situation. The good news? You can actually buy moon rocks today without being a billionaire. The bad news? If you want the "real" stuff—the rocks the Apollo astronauts actually picked up—you’re basically out of luck unless you’re okay with some serious legal heat.
The Two Types of "Moon Rocks" (And Their Prices)
To understand the price, you first have to know that "moon rock" means two very different things in the market.
There are lunar meteorites, which are chunks of the moon that got blasted off by asteroid impacts and eventually crashed into Earth (usually found in the Sahara Desert). Then there are Apollo samples, which were hand-carried back by NASA.
Lunar Meteorites: The "Affordable" Option
These are the only moon rocks you can legally buy and sell on the open market. Since they landed here on their own, NASA doesn't own them.

- Small fragments: You can find tiny "crumbs" or dust for about $25 to $50.
- Price per gram: Generally, these sell for anywhere from $150 to $1,000 per gram.
- The "pretty" ones: If a slice has a nice "fusion crust" (the charred outside from falling through our atmosphere), the price spikes.
Apollo Moon Rocks: The Price of a Felony
If you see someone selling a rock that claims to be from an Apollo mission, run. NASA considers these "National Treasures." They have never—not once—legally gifted a moon rock to an individual for private ownership.
- Official valuation: During the 2002 prosecution of some interns who stole a safe full of rocks, the government valued Apollo moon rocks at roughly $50,800 per gram in 1973 dollars.
- Modern estimate: Adjusted for 2026 inflation and scarcity, that's well over $350,000 per gram.
The Million-Dollar Exceptions
Of course, there’s always a loophole. A few years back, a tiny set of three moon rocks (about the size of rice grains) sold at Sotheby's for $855,000.
Why was this legal? Because they weren't American. They were brought back by the Soviet Union’s Luna-16 robotic probe in 1970. The USSR gifted them to the widow of Sergei Korolev (the father of the Soviet space program), and because they were a legal gift from a sovereign nation to a private citizen, they became the only "documented" moon rocks in private hands.
Then there was the case of the "accidental" bag. A woman named Nancy Lee Carlson bought a bag for $995 at a government auction that turned out to be the one Neil Armstrong used to collect the very first moon samples. It still had dust inside. After a massive legal battle with NASA, she won. She later sold it for **$1.8 million**.
Why Are They So Expensive?
It’s basic supply and demand, but on a cosmic scale.
The moon is about 238,000 miles away. Getting there is hard. Getting back is harder. Only about 842 pounds (382 kilograms) of rock was brought back during the Apollo era. To put that in perspective, that’s about the weight of a large vending machine. That’s all we have for the entire planet.
Meteorites are even rarer. For every 1,000 meteorites found on Earth, only about one is actually from the moon. Most of them are found in places like Morocco or Oman because the dark rocks stand out against the pale sand.
Spotting the Fakes
If you’re browsing eBay or a local gem show, you’ve gotta be careful. "Moon Rock" is also a common name for high-potency cannabis, which is definitely not what we’re talking about here.
For the geological kind, look for a Certificate of Authenticity (COA) from a member of the International Meteorite Collectors Association (IMCA). If a seller can't tell you the "NWA" number (Northwest Africa) or the specific classification of the rock, it’s probably just a piece of terrestrial basalt they found in their backyard.
Practical Steps for Future Collectors
If you're serious about owning a piece of the lunar surface, don't start by looking for a "rock." Start small.
- Look for "Lunar Dust" displays: Many reputable dealers sell tiny vials of dust from the cutting process of larger meteorites. These usually go for $30-$60 and are a great entry point.
- Verify the Source: Check the Meteoritical Bulletin Database. If a seller claims their rock is "NWA 11788," you can look up that exact rock to see its history and who originally found it.
- Check Auction Histories: Sites like Heritage Auctions or Christie’s have archives showing what specific slices have sold for in the last year. Use those as a price ceiling so you don't overpay.
- Avoid "Apollo" Claims: Unless you have a million dollars and a team of lawyers, any "Apollo" rock for sale is either a scam or a one-way ticket to a federal investigation.
Moon rocks are probably the only thing on Earth where the price is determined more by the "story" and the "legality" than the actual mineral content. After all, chemically speaking, a moon rock is mostly just oxygen, silicon, magnesium, and iron. But when those elements come from the Sea of Tranquility, the price tag goes to the stars.
Actionable Insights: To start your collection safely, focus on NWA-classified lunar meteorites from IMCA-member dealers. Avoid any listings that mention Apollo or NASA ownership, and always cross-reference the specimen weight with current market rates of $150–$300 per gram for common lunar breccia.
