About the Item

A Natural Iron Sculpture Shaped by Nature The sculptured Meteorite is presented on a polished, black and white flamed marble block and held in place by a strong magnet. The specimen can be removed or positioned according to the liking of the owner. DETAILS: • Weight: 128 grams • Dimensions: Ca. 70 x 55 x 25 mm • Find Date: 27th of December 2018 • Find spot: 47° 8.193’ N / 7°8.320’ E • Treatment: The Specimen’s surface has been desalinated and coated with micro layer of paraffin (reversable) • Official name: TW 1253 About the Swiss Twannberg Meteorite: • Fall occurred about 150'000 years ago or earlIer • To date (end of 2021) 2020 individual fragments have been found • Total weight 150 kilograms • Rare Hexahedrite / Octahedrite IIG iron • Worldwide there are only six meteorites classified as Hexaedrite IIG iron, out of which the Twannberg is the only European fall. • Very low nickel content of 4.5 % • High content of phosphorus within crystalline Schreibersite (Iron phosphide) • The Twannberg meteorite is by far the biggest of the eleven Swiss meteorites known to date • The strewn field is one of the largest in Europe and probably the best documented fall in the world Worldwide shipping is complimentary - There are no additional charges for handling & delivery. I am a member of the Citizen-Science-Project organized by Professor Doctor Beda Hofmann, head of Earth Sciences department, of the Natural History Museum of Berne, Switzerland, researching the strewn field of the Twannberg meteorite on the Plateau de Diesse in Switzerland. Every found meteorite is analyzed for its metallurgical composition, measured and inspected for inclusions in the oxidation crust, flow lines and other surface properties. The meteorite is given its unique number beginning with TW for ‘Twannberg’ and then returned in accordance with the agreement between the Cantone of Berne and the finder – Meaning all finds are shared, depending on weight and rarity. We search in all seasons a large area in the Bernese Jura up to about 1500 meters above sea with sophisticated metal detectors – sometimes in lovely pasture, other times we negotiate very steep, forested slopes taking considerable risks. Unfortunately, we get a huge number of false signals and dig up a considerable number of discarded and lost metal objects, such as horse and cow shoes, nails, bits of fencing, artillery fragments and bullets, rubbish, etc. To find one meteorite a searcher has to dig hundreds of false signals often in arduous conditions. Hence, we have only found 2000 individual specimens since 1984. Many finders hold on to their allocated meteorites, so few of those rare good quality specimens actually reach the open market. I am happy to pass on my larger meteorites, whilst I hold on to the small, gem quality Twannberg meteorites, which I plan to use for my new, upcoming jewelry collection. Not all specimens found are of the same quality. Being iron they are often heavily oxidized, become instable and start to crumble. However, a small percentage of meteorites fell into an area, where the acidic soil layer is very thin and sunk down on the more stable, alkaline lime gravel layer which makes up the Jura hills – virtually a more or less neutral zone. So, I would estimate about 10% of all meteorites are found, still retaining parts of their dark, outer crust after all those years. If it happens, that the spot is located high enough, i.e. out of reach of the glaciers which covered the area at least twice since the fall and mulled everything over in their path, the meteorite would wait unharmed patiently for over 150’000 years for someone to find it. If then, the meteorite is above average weight and it displays an attractive sculptured shape, we are talking about the absolute rarest possible type of Twannberg Meteorite, of which there were only a few hand full found. I am selling here a well sized, superbly sculptured, Twannberg meteorite specimen, still retainig large parts of its dark crust, coming directly out of the hands of its licensed finder (me) and certified by Prof. Dr. Beda Hofmann with the official reference number of TW 1253. Twannberg Meteorite, being the only fall of rare Hexaedrite IIG iron in Europe, as well as extremely well documented (each specimen is referenced) and internationally deeply researched, commands high prices, which are set to rise. The search campaign is nearing its end, finds are becoming noticeably rarer and considerably more difficult to make. Then not all Twannberg meteorites are stable ... during the last decade many owners of Twannberg meteorite samples had to accept that their iron meteorite turned out to be unstable once removed from the soil and the specimen degraded relatively fast to pile of rusty flakes. Also, the Twannberg fall is fast becoming known to wider circles and consequently the museums and collectors are bound to acquire a presentable, stable and well sized sample - either to put on show and/or for research purposes. All these circumstances are making this meteorite very desirable and good, stable examples will become increasingly rare on the open market.
