How Much Do Meteorites Cost?
Buying Guide
Meteorite prices vary widely depending on rarity, classification, and condition. Some common meteorites cost only a few dollars per gram, while rare planetary meteorites can reach hundreds or even thousands. Understanding what drives value is the first step to buying wisely.

Typical Price Ranges by Type
The table below offers a broad reference for current market pricing. Prices within each category can vary significantly based on specimen quality, total known weight, visual appeal, and market conditions. These ranges are for general orientation only and should not be taken as industry benchmarks or authoritative valuations.
| Meteorite Type | Typical Range (per gram) | Notes |
|---|---|---|
| Ordinary Chondrites | $1 – $5 | Most common type. Higher grades and oriented individuals command premiums. |
| Carbonaceous Chondrites | $5 – $100+ | Wide range depending on group. CIs and fresh CMs can reach significantly higher. |
| Iron Meteorites | $2 – $50 | Aesthetic slices, fine octahedrites, and rare chemical groups command the top end. |
| Pallasites | $20 – $60 | Gem-quality olivine and backlit slices push prices higher. Ungrouped specimens vary. |
| HED Achondrites | $3 – $30 | Eucrites and diogenites are relatively accessible. Howardites can be higher. |
| Lunar Meteorites | $45 – $1,000+ | Extremely rare. Pricing depends heavily on lithology, TKW, and specimen quality. |
| Martian Meteorites | $75 – $5,000+ | Among the rarest collectible material on Earth. High-quality individuals can exceed this range. |
Prices above reflect general market observations and are not a comprehensive or authoritative benchmark. Individual specimens may fall above or below these ranges based on factors specific to that piece.
What Drives Meteorite Value
No two meteorites are priced the same way. Several factors interact to determine what a given specimen is worth, and understanding them helps buyers evaluate listings with confidence.
Price Per Gram vs. Total Price
Meteorite pricing is almost always discussed in terms of price per gram, but the relationship between gram price and total cost is not always intuitive. Larger specimens from common finds often sell for less per gram because the supply is higher. Smaller fragments of a rare find can command a dramatically higher per-gram price because each gram represents a larger fraction of all material known to exist.
In meteorites, rarity and identity matter as much as weight. A one-gram slice of a confirmed Martian meteorite is worth more than a kilogram of common chondrite material by a considerable margin.
Presentation also affects per-gram pricing. A well-cut, polished, and photographed specimen with attractive fusion crust or visible chondrules will typically sell for more per gram than an equivalent mass of broken fragments, even from the same meteorite.
Witnessed Falls vs. Finds
Meteorites are divided into two broad recovery categories: falls and finds. A witnessed fall is a meteorite recovered after being observed entering the atmosphere and landing. Finds are meteorites discovered on the surface without any observed fall event, often years or decades after landing.
Witnessed falls are generally more desirable because they are recovered quickly, before terrestrial weathering begins. Fresh fall material often retains pristine fusion crust, unweathered interior texture, and, in the case of carbonaceous chondrites, volatile compounds that would otherwise degrade. This freshness carries a measurable premium in the market.
Desert finds are graded by weathering level (W0 through W6). Low-weathering specimens with intact fusion crust and minimal rust or alteration are significantly more desirable than heavily weathered material of the same classification.
Why This Matters for Collectors
Understanding price ranges helps buyers recognize the difference between common material, genuinely premium specimens, and listings that are either unrealistic or suspicious. A common ordinary chondrite listed at $200 per gram is overpriced by a wide margin. A Martian meteorite offered at $10 per gram warrants serious scrutiny.
Pricing that seems too high for the type usually signals a seller banking on a buyer's unfamiliarity with the market. Pricing that seems too low for a rare type is a reason to ask harder questions about classification, documentation, and authenticity.
The most reliable protection for a collector is a basic familiarity with what each meteorite type actually costs, combined with a seller who is transparent about classification source, specimen weight, and provenance.

Frequently Asked Questions
Why are some meteorites so expensive?
Rare classifications, low total known weight, scientific importance, and strong collector demand can make some meteorites extremely valuable. Lunar and Martian meteorites in particular are rare by any measure, and their per-gram prices reflect that scarcity.
Are lunar meteorites more expensive than ordinary meteorites?
Yes, significantly. Lunar meteorites are far rarer than ordinary chondrites and generally command much higher prices per gram. The specific lithology, total known weight, and specimen quality all affect where within the lunar price range a particular piece falls.
Does a bigger meteorite always cost more per gram?
Not necessarily. Larger pieces from abundant finds often sell for less per gram because supply is higher. Rare meteorites from small finds may cost more per gram in any size, as each gram represents a larger share of all known material.
What is total known weight and why does it matter?
Total known weight (TKW) is the combined mass of all recovered material from a given meteorite. A low TKW means less material exists in total, which typically drives per-gram prices higher regardless of classification.
Are unclassified meteorites worth buying?
Unclassified meteorites can still be genuine extraterrestrial material and are a legitimate part of the market. They typically sell for less than classified specimens of similar appearance because their scientific identity has not been formally established. Buying unclassified material from a trusted source with transparent documentation is the key consideration.
How can I tell if a meteorite is priced fairly?
Familiarizing yourself with typical per-gram ranges by type is the most effective starting point. A seller who is transparent about classification, provenance, and specimen weight, and whose pricing aligns with known market ranges, is a good sign. Prices that seem dramatically above or below market for a given type deserve closer scrutiny.
