Why eBay for Meteorite Hunting? The Pros and Cons
eBay, a global online marketplace, offers several compelling reasons to consider it for purchasing meteorites, alongside some crucial caveats:
Pros:
- Accessibility and Variety: eBay boasts an unparalleled selection of meteorites from sellers worldwide. From common chondrites to rare pallasites and lunar meteorites, the sheer variety is astounding. This accessibility allows buyers to explore different types, sizes, and price points, catering to various budgets and collecting interests.
- Competitive Pricing: The auction and "Buy It Now" formats on eBay can foster competitive pricing. Sellers often compete to attract buyers, potentially leading to better deals compared to specialized meteorite dealers. However, remember that "cheap" doesn't always equate to "genuine" in the meteorite world.
- Direct Seller Interaction: eBay facilitates direct communication with sellers. You can ask questions about the meteorite's origin, classification, and authenticity, gaining valuable insights before making a purchase.
- Established Platform: eBay's established platform offers buyer protection mechanisms and secure payment gateways, providing a degree of security compared to less regulated online marketplaces.
Cons:
- Authenticity Concerns: This is the biggest hurdle. eBay's open nature means that counterfeit or misidentified items can surface. Distinguishing genuine meteorites from "meteor-wrongs" (Earth rocks that resemble meteorites) requires expertise and vigilance. Scams, while not rampant, are a potential risk.
- Seller Reliability: Seller reputation varies widely on eBay. Some sellers are reputable meteorite experts and dealers, while others may lack expertise or even be intentionally deceptive. Thoroughly vetting sellers is crucial.
- Information Overload and Misinformation: The sheer volume of listings can be overwhelming. Misleading descriptions, inaccurate classifications, and exaggerated claims can be prevalent. Buyers need to be critical and verify information independently.
- Shipping and Handling: Meteorites, especially larger specimens, can be heavy and require careful packaging for safe transit. Shipping costs can be significant, and potential damage during shipping is a concern.
Navigating the Cosmic Catalog: Understanding Meteorite Types
Before diving into
1. Stony Meteorites (Aerolites):
The most common type, comprising about 95% of all meteorites found. They are primarily composed of silicate minerals. Subcategories include:
- Chondrites: These are undifferentiated meteorites, meaning they represent the primordial material of the early solar system, largely unchanged since their formation. They contain chondrules, small, spherical inclusions that are a defining characteristic. Ordinary chondrites, carbonaceous chondrites, and enstatite chondrites are common subtypes.
- Achondrites: These are differentiated meteorites, meaning they have undergone melting and differentiation processes similar to planets. They lack chondrules and are often basaltic or plutonic in composition. Lunar meteorites, Martian meteorites, and HED meteorites (Howardites, Eucrites, Diogenites) are significant achondrite groups, often originating from the Moon, Mars, and asteroid 4 Vesta, respectively.
2. Iron Meteorites (Siderites):
Composed mainly of iron and nickel alloys, with minor amounts of other elements. They represent the cores of differentiated asteroids. Iron meteorites exhibit characteristic Widmanstätten patterns when etched, a unique crystalline structure formed by slow cooling over millions of years.
3. Stony-Iron Meteorites (Siderolites):
A fascinating mix of both stony and iron material, representing the core-mantle boundary of differentiated asteroids. Subcategories include:
- Pallasites: Spectacular meteorites containing olivine crystals (often peridot) embedded in a nickel-iron matrix. Pallasites are highly prized for their beauty and rarity.
- Mesosiderites: Contain roughly equal amounts of silicate and metallic material, often brecciated and more complex in structure than pallasites.

The Authenticity Imperative: Verifying Your Cosmic Purchase
Authenticity is paramount when buying meteorites, especially on a platform like eBay. Here's a comprehensive strategy to minimize the risk of acquiring a "meteor-wrong" or a fake:
1. Scrutinize the Seller:
- Seller Feedback and Reputation: Check the seller's feedback score and read reviews carefully. Look for sellers with a high positive feedback percentage and a history of selling meteorites or related items. Long-standing sellers with consistent positive feedback are generally more trustworthy.
- Seller Expertise and Description Details: Does the seller demonstrate knowledge of meteorites in their listings? Are descriptions detailed and informative, going beyond just "meteorite for sale"? Look for information on classification (if known), find location (if available), weight, dimensions, and any distinguishing features.
- Ask Questions: Don't hesitate to contact the seller with specific questions. A reputable seller will be happy to answer your inquiries and provide additional information or photos. Be wary of sellers who are evasive or unwilling to provide details.
2. Examine the Listing Critically:
- High-Quality Photos from Multiple Angles: Listings should include clear, well-lit photos of the meteorite from various angles, showcasing its surface features, fusion crust (if present), and any unique characteristics. Beware of listings with blurry or limited photos.
- Detailed Description and Provenance: A good description should detail the meteorite's characteristics, potential classification (if known), and ideally, any available provenance (history of ownership and find location, if known). Claims of witnessed falls or specific locations should be substantiated.
- Certificate of Authenticity (COA): While not foolproof, a COA from a reputable meteorite laboratory or dealer can add a layer of assurance. However, verify the credibility of the issuing entity. COAs from unknown or unverified sources are of little value.
- Price Comparison: Research comparable meteorites online and from reputable meteorite dealers to gauge if the price is reasonable. Extremely low prices for rare types should raise red flags. "If it seems too good to be true, it probably is" applies strongly to meteorites on eBay.
3. Recognize Meteorite Characteristics (and "Meteor-Wrongs"):
- Fusion Crust: Many meteorites, especially freshly fallen ones, exhibit a fusion crust – a thin, dark, glassy layer formed by melting during atmospheric entry. However, fusion crust can weather away over time.
- Regmaglypts (Thumbprints): Indentation-like features on the surface of some meteorites, resembling thumbprints, caused by ablation during atmospheric entry.
- Weight and Density: Meteorites are typically denser than most Earth rocks due to their metallic content. A rock that feels unusually heavy for its size could be a meteorite (but density alone is not definitive).
- Absence of Vesicles (Bubbles): Meteorites generally lack vesicles or air bubbles common in terrestrial volcanic rocks.
- Magnetic Properties: Most meteorites (especially iron and stony-iron meteorites, and many chondrites) are magnetic due to their iron-nickel content. However, some Earth rocks are also magnetic, so this test is not conclusive on its own.
"Meteor-Wrongs": Be aware of common "meteor-wrongs" – terrestrial rocks that are often mistaken for meteorites. These include:
- Iron Ore (Hematite, Magnetite, Limonite): Heavy, magnetic, and can have a dark appearance, but often lack fusion crust and other meteorite characteristics.
- Slag: Industrial waste products from smelting, often glassy or metallic, but lack the internal structure and composition of meteorites.
- Basalt and other Volcanic Rocks: Dark-colored rocks that can sometimes resemble meteorites superficially, but are typically less dense and lack fusion crust.
4. Consider Professional Verification (Post-Purchase):
For higher-value meteorites or if you have any lingering doubts, consider sending a small sample to a reputable meteorite laboratory for analysis and classification. Organizations like the Meteoritical Society maintain lists of qualified laboratories. This is an additional expense but provides the ultimate confirmation of authenticity.
Decoding the Cosmic Price Tag: Factors Influencing Meteorite Value
The price of meteorites on
- Rarity: Rarity is the most significant price driver. Lunar meteorites, Martian meteorites, pallasites, and certain types of carbonaceous chondrites are significantly rarer and more valuable than common ordinary chondrites.
- Type and Classification: As discussed earlier, different meteorite types have varying levels of rarity and scientific interest, impacting their value.
- Size and Weight: Larger and heavier meteorites generally command higher prices, especially for display specimens. However, price isn't always linearly proportional to weight; smaller, aesthetically pleasing pieces or scientifically significant fragments can be very valuable.
- Condition and Aesthetics: Well-preserved meteorites with intact fusion crust, interesting shapes, or aesthetically pleasing features are more desirable and valuable. Weathering, fractures, or damage can reduce value.
- Origin and Provenance: Meteorites with documented falls, known find locations, or historical significance can be more valuable. Lunar and Martian meteorites, due to their extraterrestrial origin, are inherently valuable.
- Supply and Demand: Like any collectible market, meteorite prices are influenced by supply and demand. Discoveries of new meteorite finds or increased collector interest can impact prices.
Price Ranges (General Guidance):
- Common Ordinary Chondrites: Can range from a few dollars per gram for smaller, unclassified fragments to tens of dollars per gram for larger, aesthetically pleasing specimens.
- Iron Meteorites: Similar price range to ordinary chondrites, depending on size, aesthetic appeal (Widmanstätten pattern), and type.
- Pallasites: Significantly more expensive, often starting at hundreds of dollars per gram and reaching thousands for exceptional specimens due to their rarity and beauty.
- Lunar and Martian Meteorites: The most expensive, typically ranging from hundreds to thousands of dollars per gram, and sometimes even more for exceptional specimens.
Caution: These are very general price ranges. Always research comparable meteorites and consult with reputable dealers for accurate valuations. Be wary of listings that seem significantly overpriced or underpriced compared to market averages.
