UREILITE - Primitive Achondrite - (With nano diamonds!) Complete piece. WITHOUT RESERVE PRICE. - 12.2 g

La ureilita es un tipo raro de meteorito pedregoso que tiene una composición mineralógica única muy diferente a la de otros meteoritos pedregosos. Este tipo de meteorito de color gris oscuro o marrón lleva el nombre de la aldea Novy Urey, República de Mordovia de Rusia, donde un meteorito de este tipo cayó el 4 de septiembre de 1886. Las ureilitas se clasifican como meteoritos del tipo acondritas primitivas, que son un sub-grupo muy raro y escaso dentro de los meteoritos. La anécdota cuenta cómo algunos trabajadores del campo vieron caer el meteorito, lo recogieron, lo machacaron y comieron algunos fragmentos. Lo curioso es que las ureilitas tienen fama por ser los meteoritos más duros del mundo, debido a que contienen pequeños diamantes en su interior, y esto hace que sea casi imposible de cortarlos, a pesar de usar hilo de diamante para tal trabajo. Están compuestas por olivino (50-75 %) y piroxeno (14-35 %) y muy poca cantidad de metales de Fe y Ni. Entre los cristales de estos minerales, en la matriz, se encuentran gases nobles y carbono (a veces en forma de diamante, que es un indicador de altas presiones). La presencia de diamantes se ha interpretado como el resultado de la metamorfización de grafito. Una oportunidad para añadir esta maravilla del universo a tu colección. Todos nuestros meteoritos van acompañados de un certificado de IMCA (Asociación Internacional de Coleccionistas de Meteoritos) por lo que garantizamos la autenticidad de todos nuestros meteoritos de por vida. Compre con garantías. Saludos y nuestros mejores deseos. CRATER METEORITES

The 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 dark gray or brown meteorite is named after the village Novy Urey, Republic of Mordovia in Russia, where a meteorite of this type fell on September 4, 1886. Ureilites are classified as primitive achondrite type meteorites, which are a very rare and scarce sub-group within meteorites.

The anecdote tells how some farm workers saw the meteorite fall, picked it up, smashed it, and ate some fragments. The curious thing is that ureilites are known to be the hardest meteorites in the world, because they contain small diamonds inside, making them almost impossible to cut, even when using diamond wire for such work.

They are composed of olivine (50-75%) and pyroxene (14-35%) and very small amounts of Fe and Ni metals. Among the crystals of these minerals, in the matrix, noble gases and carbon (sometimes in the form of diamond, which is an indicator of high pressures) are found. The presence of diamonds has been interpreted as the result of the metamorphosis of graphite.

An opportunity to add this wonder of the universe to your collection.

All our meteorites come with a certificate from IMCA (International Meteorite Collectors Association), which guarantees the authenticity of all our meteorites for life. Buy with confidence.

Greetings and our best wishes.
