Piece of great beauty with a visible octahedrite shape in which the metal has crystallised. Besides, it has a polished face where you can see a Widmanstätten pattern and Neumann lines.
In fact, Muonionalustas are often used in jewellery making due to their great beauty
The meteorite collided with Earth 1,000,000 years ago, between Finland and Sweden. It is the oldest meteorite known on Earth. The first stories of its existence reached scientific circles in 1906.
Iron meteorites are composed mainly of iron and nickel.
Actually, they are a piece of an asteroid core. In the differentiation process, when the asteroid is a ball of magma, during its formation, iron and nickel settle to the core of the asteroid, as they are the heaviest elements. After cooling, the asteroid metal core is formed. Through catastrophic collisions, the asteroid and its core break and the fragments remain in space, until a piece falls to our planet. They are estimated to account for 5.7% of falls.
At Expometeoritos, we take care of dissemination, talks, workshops, analysis, classification and exhibitions of meteorites.
We are members of:
.- IMCA (International Meteorite Collectors Association) #8187
.- Meteoritical Society
.- American Meteor Society
All our pieces are certified and, if the value of the piece is over €300, we also provide its chemical composition analysis, carried out in our facilities by X-ray spectrography.
