This subject came up in another forum recently, and I am glad to see it here as well. It needs to keep coming up and be repeated until the crooked line is straightened out. I have seen all of your examples on ebay and with increasing frequency in the last year. At best it is sloppy and impulsive, and at worst, it is flat out dishonest. Collectors and dealers alike need to be steadfast in their vigilance against the degradation of planetary collections. Indeed Adam, they are not commodities. We all need to educate our colleagues, students, friends and clients. Refuse to buy or sell these cheap, unproven, unclassified, falsely paired, or fake stones, call them out, and stay true to the protocols of science (after all, we are not politicians are we?!).

Unofficial, untested and unverified material carries a lot of risks since it is basically worthless in a secondary market where knowledgeable collectors and museums avoid it. Every statement below also applies to other meteorites including Martian material which I stopped listing several years ago due to a high degree of fraudulent listings interfering with officially studied material. These less than truthful offerings hurt honest dealers and collectors alike. Real Lunar Meteorites Are Exceedingly Rare: I will start off by stating that Lunar Meteorites are not commodities. There is no set price per gram since they differ greatly from one another with varying degrees of provenance, scientific importance, weathering, preparation, history and aesthetic qualities to name few variables. Genuine meteorites from the Moon are exceedingly rare, millions of times rarer than diamonds. Would you buy a diamond without proper certification from a reputable laboratory? I didn?t think so. The total official mass of all lunar meteorites combined is 177 kilograms or 390 pounds consisting of 139 meteorites while the combined weight of diamonds can be measured in metric tons. The Problem Started In 2102 Beginning Around NWA 7XXX: The few lunar meteorite examples that were discovered before 2012 were managed properly for the most part. It was not until around 2012, starting with Northwest Africa (NWA) series numbers exceeding NWA 7000, that real problems started to take place frequently. Moroccan dealers, acting as middlemen for the finders in Northwest Africa, began offering material directly at the big Gem and Mineral shows like Tucson and Denver with piggy-backed (stolen) nomenclature (NWA numbers.) They fraudulently adopted these numbers based on visual appearance alone to official meteorites that were actually studied, peer-reviewed and listed in the Meteoritical Bulletin. They completely bypassed the Meteoritical Society and the Nomenclature Committees violating protocols set in place to protect collectors and scientific laboratories. Reputable dealers used to acquire ?stones? directly from Northwest Africa, submit a type specimen to a recognized laboratory, wait for the laboratory results and then wait some more for the Nomenclature Committee to assign an official name before placing meteorites on the market. Notice I used the word ?stones? instead of Lunar Meteorites. This is because the convention among professionals is that you cannot call a stone a meteorite until it has gone through the proper protocols. Genuine lunar meteorites are far too important to bypass this process that has been in place longer than these so-called ?dealers? who place untested and unproven material on the market. Terms That should Raise Serious Concerns: Paired ? If the dealer?s name doesn?t match the name listed in the Meteoritical Bulletin for the pairing number he/she is using, then a provenance check is imperative. The dealer should provide you with a complete chain of custody back to the name provided in the Bulletin. If they cannot provide this information, then it is not worth pursuing. Likely Paired ? In other words, no scientist or laboratory has looked at it and likely never will meaning it is worthless. Provisional ? Is supposed to mean that it is waiting for official classification and nomenclature assignment. If it were a genuine lunar meteorite, then why can?t the dealer wait to have it made official? Classification Pending ? Another way of saying the stone is not official and has not been formally classified. If a classification were really pending, a reputable dealer would simply wait before releasing it to the market. Unclassified Lunar ? I like this one since it sounds honest at first glance. A more honest statement is that it looks like a lunar to me but you will have to send in a 20% or 20 gram type sample to a Meteoritical Society approved laboratory, pay the fees and wait a year to find out if it is indeed a lunar meteorite. Will Be Studied ? I would ask the dealer by who and when? Identical To ? Means absolutely nothing without laboratory confirmation. Things To Watch Out For: No Name ? Means it has not been studied and more than likely is a terrestrial stone. Improper Name ? Some use NWA XXXX instead of a number or worse yet, use official sounding names that they came up with themselves. It is best to avoid this type of material. Uncut Stones And Fragments ? How could it have been studied when a cut surface is required to perform laboratory classification work and deliver a type specimen to make it official? At the very least, you should be provided with the scientist?s name and contact information, for verification purposes, that determined that these exact uncut stones and fragments that are being offered are indeed lunar meteorites in their opinion. Ridiculously Cheap Buy-It-Now Prices ? You have heard the saying ?If it sounds too good to be true, then it probably isn?t.? Just check on eBay for real lunar meteorites that predate 2012/NWA 7000 with good provenance and you will see that the prices are about ten to twenty times higher. This is because they are much more likely to be genuine, were managed properly and the correct steps were taken in their formal classifications. These older NWA lunar meteorites are also well-established with collectors, museums and the scientific community who are all now somewhat leery of the most recent offerings with a very poor track record thus far. The main problem is that would-be buyers now have to wade through hundreds of listings to find valid, well-managed and official lunar meteorites. Another old saying is, ?You get what you pay for.? Not Enough Information ? Some dealers simply post a Meteoritical Bulletin entry in their descriptions and do not discuss how they came into possession of the material. If the person?s name in the entry doesn?t match theirs, a satisfactory explanation is required for provenance purposes. Some simply claim, ?from the finder to you? which means there is absolutely no scientific verification whatsoever and what they are offering is basically worthless. It is up to the dealer to provide the entire chain of custody in their auction descriptions up front. Why should a prospective buyer have to ask for this information? Number Of Stones Exceeds Meteoritical Bulletin Entry ? It is interesting that some of these self-paired uncut stones or fragments are being offered by the dozens under the same NWA number when much less than the number offered on eBay is listed in the Meteoritical Bulletin. Lousy Material Preparation - It has been my experience that dealers who do not have enough pride to finish slices by polishing out saw marks also take other shortcuts including not getting their material formally classified. Saw marks are a good indication the dealer is not interested in presentation, just a quick buck. Online Provenance Check ? You can get information online by simply typing in the words ?Meteoritical Bulletin? into a search engine like Google. You will find the Meteoritical Society?s database where you can enter the NWA number or name of any meteorite in question. If concerned about authenticity, ask dealers these simple questions: ?Has this exact specimen you are selling as lunar, been officially classified?? ?What is the name of the institution that classified this exact specimen you have paired to another official meteorite?? ?What is its official pairing number or name?? ?If paired, what laboratory made the official pairing and what is the name of the scientist that looked at this exact stone?? ?Can I directly contact the institution who studied this stone?? ?Can you direct me to the specific official documentation that proves your offering has been properly studied and classified and not that of the stone you have this paired to?? ?Will you provide a lifetime guarantee that this is indeed what you say it is? ?How could this specimen have been studied when there are no windows or cuts to expose the interior? ?Why have you not included an ID card with your name on it, is there something to hide?? Hope this helps some from being taken! Received on Fri 06 Oct 2017 04:56:46 PM PDT |
