1. Type
Meteorite classification significantly impacts value. Categorization hinges on composition: stony, iron, stony-iron, and further subdivisions based on mineralogy, structure, and origin. This categorization is crucial for determining market value.
-
Chondrites
The most common type, chondrites, are stony meteorites containing chondrules, small spherical inclusions. Their abundance generally results in lower values, often priced per gram, ranging from a few dollars to tens of dollars depending on specific subtypes and features like visible chondrules or a fresh, unweathered exterior.
-
Achondrites
Stony meteorites lacking chondrules, achondrites, represent differentiated bodies, often originating from asteroids or planets. This group includes meteorites from the Moon and Mars, significantly increasing their value due to rarity. Lunar and Martian meteorites can command prices reaching thousands of dollars per gram.
-
Iron Meteorites
Composed primarily of iron-nickel alloys, iron meteorites showcase unique crystalline patterns known as Widmansttten patterns upon etching. Their aesthetic appeal and relative scarcity compared to chondrites contribute to higher values, generally ranging from tens to hundreds of dollars per gram depending on the specific type and aesthetic qualities of the etched pattern.
-
Stony-Iron Meteorites
Representing a mixture of stony and iron materials, this rare category includes pallasites and mesosiderites. Pallasites, with their translucent olivine crystals embedded in an iron-nickel matrix, are highly prized by collectors, often fetching hundreds or even thousands of dollars per gram. Mesosiderites, with a more complex mix of silicates and metal, also hold significant value.
Understanding the specific type is fundamental for evaluating a meteorite. Rarity and scientific significance associated with certain types, like lunar and Martian meteorites or pallasites, drive prices significantly higher than common chondrites. Therefore, accurate classification is the cornerstone of determining a meteorite’s monetary and scientific worth.
2. Rarity
Rarity significantly influences meteorite valuation. The scarcity of specific types directly correlates with their market price. Common chondrites, representing the vast majority of meteorite falls, are readily available, resulting in lower prices. Conversely, meteorites originating from the Moon, Mars, or other differentiated parent bodies are exceptionally rare, driving their value considerably higher. For example, only a few hundred kilograms of confirmed Martian meteorites exist globally, making them highly sought-after specimens. This scarcity creates a premium, with prices potentially reaching thousands of dollars per gram. Similarly, pallasites, a rare type of stony-iron meteorite, are prized for their beauty and scarcity, also commanding substantial prices.
The degree of rarity also extends to subtypes within broader classifications. For instance, certain carbonaceous chondrites, known for their primitive composition and potential to hold clues about the early solar system, are rarer than ordinary chondrites and therefore more valuable. Furthermore, witnessed falls, where the meteorite’s descent is observed and documented, often increase the value compared to finds, where the meteorite’s fall was not witnessed. This is because witnessed falls typically result in faster recovery, leading to less weathering and better preservation. A well-documented provenance, including details of the fall and subsequent handling, enhances a meteorite’s value, especially for rarer types.
Understanding the interplay between rarity and value is crucial for both collectors and researchers. This knowledge allows for informed decisions regarding acquisition and research priorities.

Ultimately, rarity remains a key determinant of a meteorite’s significance and desirability, shaping its value within the scientific community and collector market.
3. Size/Weight
Size and weight directly influence meteorite valuation. Larger specimens are generally more valuable, assuming all other factors (type, rarity, etc.) remain equal. This is partly due to the inherent appeal of possessing a substantial piece of extraterrestrial material. However, the relationship isn’t strictly linear. A large, common chondrite might not be as valuable as a small piece of a rare lunar meteorite. Value increases with size, but the type and rarity play a more significant role. For example, a single large individual from a witnessed fall is typically more valuable than a combined weight of smaller fragments from the same event, even if the total weight of the fragments exceeds the single piece. This is because complete individuals are often more scientifically valuable and aesthetically appealing.
The practical significance of understanding the size/weight relationship lies in assessing the potential value of a meteorite. A large iron meteorite, even if relatively common, can still command a substantial price due to its size. Conversely, a small fragment of a rare type can be exceptionally valuable despite its diminutive size. For instance, a few grams of a Martian meteorite, even a small fragment, can be worth more than a kilogram of a common chondrite. This understanding is crucial for collectors, researchers, and dealers alike, enabling informed decisions regarding acquisition, sale, and research priorities. The mass of a meteorite is also a critical factor in museum acquisitions and scientific studies, where larger samples can provide more material for analysis and research.
In summary, while size and weight contribute to a meteorite’s value, they must be considered in conjunction with other factors like type and rarity. Larger specimens are generally more desirable, but rarity often outweighs size in determining overall value. This nuanced relationship highlights the complexity of meteorite valuation and the importance of considering all relevant factors when assessing a specimen’s worth. The practical implications of this understanding are significant for anyone involved in the collection, study, or trade of these fascinating remnants of our solar system.
4. Condition (Weathering)
A meteorite’s condition, specifically its degree of weathering, significantly impacts its value. Weathering refers to the terrestrial alteration a meteorite undergoes after its fall, primarily due to exposure to the elements. Freshly fallen meteorites exhibit minimal weathering, preserving features like fusion crust, a thin, glassy outer layer formed during atmospheric entry. Over time, exposure to water, oxygen, and other environmental factors leads to rusting in iron meteorites and chemical alteration in stony meteorites. This weathering process can obscure diagnostic features, diminishing scientific value and aesthetic appeal, thus affecting price. A heavily weathered meteorite, even a rare type, will typically be less valuable than a pristine example of a more common type. For instance, a fresh chondrite with a well-preserved fusion crust will command a higher price than a heavily weathered iron meteorite, even if the latter is inherently rarer. This underscores the importance of condition in meteorite valuation.
The effects of weathering vary depending on the meteorite’s composition and the environment where it landed. Iron meteorites are particularly susceptible to rust, which can penetrate deeply into the metal, compromising structural integrity and obscuring the Widmansttten patterns crucial for classification. Stony meteorites can experience chemical changes, leading to discoloration, disintegration, and the formation of secondary minerals. Arid desert environments offer the best preservation conditions, while humid, tropical environments accelerate weathering processes. Consequently, meteorites recovered from deserts often exhibit minimal weathering, retaining valuable scientific information and commanding higher prices. Conversely, meteorites found in humid regions might show significant weathering, reducing their value despite their potential scientific importance. This highlights the critical role of recovery location and subsequent storage conditions in preserving meteorite integrity.
Evaluating weathering requires careful observation and, in some cases, specialized analysis. Visual inspection can reveal the presence of rust, discoloration, or other signs of alteration. Microscopic examination can further assess the extent of weathering and identify secondary minerals formed during terrestrial alteration. Understanding the degree of weathering is crucial for accurate valuation and scientific interpretation. A well-preserved meteorite provides more reliable data for research and commands a higher price in the collector market. Conversely, heavily weathered meteorites, while still potentially valuable for scientific study, typically fetch lower prices.
