x 10 UREILITE Meteorite -Primitive Achondrite- (With nano...

Ureilite is a rare type of stony meteorite that has a unique mineralogical composition very different from that of other stony meteorites. This type of meteorite, dark gray or brown in color, is named after the village of Novy Urey, Republic of Mordovia, Russia, where a meteorite of this kind fell on September 4, 1886. Ureilites are classified as primitive achondrite meteorites, a very rare and scarce sub-group within meteorites. The anecdote describes how some field workers saw the meteorite fall, they collected it, ground it up, and ate some fragments. The curious thing is that ureilites are famous for being the hardest meteorites in the world, because they contain small diamonds inside them, which makes them almost impossible to cut, even when using diamond wire for the task. They are composed of olivine (50-75%) and pyroxene (14-35%) and very small amounts of Fe and Ni metals. Between the crystals of these minerals, in the matrix, noble gases and carbon are found (sometimes in the form of diamond, which is an indicator of high pressures). The presence of diamonds has been interpreted as the result of metamorphism of graphite. An opportunity to add this lot with these wonders of the universe to your collection. Also special for resale. Recently found in Ouargla (Algeria) in 2025 and officially undergoing classification. All our meteorites come with an IMCA certificate (International Meteorite Collectors Association), guaranteeing the authenticity of all our meteorites for life. Buy with guarantees. Regards and best wishes. CRATER METEORITES
