How Much Is a Meteorite Worth? A Value Guide (Price Per Gram)
“How much is a meteorite worth?” has no single answer — value runs from under a dollar a gram for common iron to over a thousand dollars a gram for a lunar meteorite. What sets the price is type, rarity, documentation, and condition. Here’s a clear, honest breakdown, including what to do if you think you’ve found one.
The short answer (price per gram)
Meteorites are usually valued per gram. As a rough guide: common irons are cheap, pallasites and witnessed stony falls cost more, and lunar/Martian material is in a league of its own. Size, beauty, and paperwork then move a piece up or down from these baselines.
What determines a meteorite’s value
- Type & rarity. Lunar, Martian, and pallasites are the rarest and most valuable; common irons are the most affordable.
- Classification & documentation. A classified, certificated meteorite is worth far more than an unidentified rock.
- Size & completeness. Complete individuals with full fusion crust, or large display slices, command premiums.
- Aesthetics. A crisp Widmanstätten pattern or bright, stable olivine raises value.
- Witnessed fall & provenance. Meteorites seen to fall, or with notable history, are prized.
- Condition. Rust and damage reduce value; stable, well-preserved pieces hold it.
Value by meteorite type
| Type | Rough value / gram | Examples |
|---|---|---|
| Common iron | ~$0.50 – $5 | Campo del Cielo, Gibeon, Muonionalusta |
| Ordinary stony (chondrite) | ~$2 – $20 | Many witnessed falls |
| Pallasite (stony-iron) | ~$5 – $40+ | Seymchan, Brenham |
| Rare achondrite / historic fall | $20 – $100+ | Famous named falls |
| Lunar / Martian | $500 – $1,500+ | Among the rarest materials on Earth |
Figures are broad market estimates to set expectations, not appraisals; real prices vary with size, quality, and documentation.
I think I found a meteorite — what’s it worth?
Be realistic first: the vast majority of suspected finds are “meteorwrongs” — slag, iron ore, hematite, or magnetite. Quick checks: a genuine meteorite usually has a dark fusion crust, is unusually dense, attracts a magnet (most do), and may show regmaglypts(thumbprint dents). It won’t be full of bubbles or vesicles. If it passes, get it examined by a university geology department or a classification lab. Only a classified, documented meteorite has real market value — see how to tell if a meteorite is real.
Value myths to ignore
- “All meteorites are priceless.” Common irons are genuinely affordable — rarity in the cosmic sense doesn’t equal a high price.
- “Bigger always means more valuable.” A small lunar fragment beats a large common iron. Type matters more than mass.
- “Magnetic = valuable meteorite.” Plenty of ordinary earth rocks are magnetic. Magnetism is one clue, not proof.
- “No paperwork needed.” Without classification or a certificate, value — and salability — drop sharply.
Buying & selling without overpaying
Whether you’re buying a specimen or a piece of jewelry, pay for what actually adds value: genuine, classified material, good condition, and documentation — not vague “rarity” claims. For jewelry specifically, remember the meteorite is usually the small part of the price; the band and design cost more, as the ring price guide explains. And always read the certificate before you pay.
Frequently asked questions
- Common iron meteorites like Campo del Cielo or Gibeon are often worth roughly $0.50–$5 per gram. Finer, jewelry-grade irons (Muonionalusta, Gibeon slices) run higher. Stony meteorites and witnessed falls can be $2–$20+ per gram, pallasites $5–$40+ per gram, and rare lunar or Martian meteorites hundreds to over a thousand dollars per gram.
