The highest quality "as found" specimens are of greatest interest to scientists, meteorite collectors, and mineral collectors. In addition, the supply of these materials is so small, so fragmented, and so unreliable that they do not have a place with wholesale or mass-market jewelers. Why are they so inexpensive? Most people are not familiar with them, so they are not being requested in jewelry stores. Who Buys Extraterrestrial Gems?Įven though these materials are extremely rare, they can typically be purchased at a lower price than some of the most popular gemstones. Because of these fractures, it can be difficult to find pieces of extraterrestrial olivine that are large enough to facet - but many faceted stones have been produced!

The stresses placed on a meteorite during its formation, its travel through space, entry into Earth's atmosphere, and impact with Earth's surface all have a chance of fracturing the olivine crystals. The pallasite material comes from a portion of that body near the core-mantle boundary. This composition suggests that it was once part of a planet or other large body of our solar system that had a metallic core and a rocky mantle. It consists of yellowish green olivine crystals, some of which are gem-quality peridot, in a matrix of meteoritic iron. This meteorite was found by a farmer working his field, and when unearthed, it weighed about 1500 pounds. The meteorite will be named after Gianfranco and Pino.Pallasite Meteorite Slice: This is a photo of a thin slice cut from the Esquel pallasite meteorite that fell near Chubut, Argentina. “It’s incredible that fragments of rock from space have now fallen on the city of stone.” “Matera is one of the oldest cities in the world, where many discoveries have been made,” he said. In January 2020, one was found near Modena in Emilia-Romagna.ĭomenico Bennardi, the mayor of Matera, a city famous for its sassi, cave dwellings carved out of limestone, said the discovery had triggered much “enthusiasm and emotion” among residents. This is the second time in recent years that a meteorite has fallen in Italy. “The material, which is soft, much like sand, is very pure, as it did not touch soil or water – it is almost as if we collected it directly from space.” “We have to analyse the remnants of the meteorite, but what is unique with this one is the situation in which it was found,” said Falco. It is also rare for meteorites to fall in an area from which their fragments can be easily recovered. More than 70 grams of the fragments have so far been gathered for study, which will eventually be put on display in a museum.Ĭarmelo Falco, a representative of Prisma who travelled to Matera straight away, said that while many meteorites hit the Earth, what is rare about the event in Matera is that the meteorite landed on a clean surface, so it has not been contaminated.įragments of the Matera meteorite. The meteorite’s fireball had been observed on the surveillance cameras of Prisma, a project run by the Italian institute of astrophysics, enabling experts to track where it might have fallen. Never would we have expected it to have been a meteorite.” “She was worried, but it was quite a windy day and so thought it might have been the branch of a tree. “I wasn’t at home when it happened, but my mother was in the basement at the time and heard a loud bang,” said Gianfranco. Not that they realised at first: the two were carrying out checks on the property’s solar panels when, three days later, they noticed a damaged panel and tile, along with grey fragments scattered across the balcony.
