Hi there, I am selling this Amazing Munonionalusta Iron Meteorite Carved Slice which would be perfect for wire wrapping as a pendant!
It is plated in rhodium to guard against corrosion.
Meteorites are one of the RAREST materials on earth, more rare than diamonds!!!!
This one fell in Sweden. The Widmanstatten pattern is a crystal structure that occurs only in the iron-nickel meteorites.
For this to form, the parent body has to be large enough that most of it's metal content melted and sank to the core, then slowly cooled over millions of years.
Then at some point, this large body was destroyed and shattered, eventually raining pieces of itself down on Earth.
When you hold this sphere in your hand, you are holding the core of a small planet that no longer exists!
This is one of the most prized possessions I have and I know it would make an AMAZING addition to any collection of ANY type,
but especially of meteorites and stones! Don't let this one pass you by. Anyway, I am offering it here, now, for you.
Hopefully this will find a great home out there, and make someone thrilled.

I am a member of the IMCA or the International Meteorite Collector's Association. This is an organization that is a check and balance of those who collect, trade and sell meteorites. You can only join this organization by having the utmost integrity. You must to have two references from existing members to get in and a good reputation. Members of this organization maintain a high standard by monitoring each others' activities for accuracy and honesty. It is every IMCA member's responsibility and pleasure to offer help and assistance to fellow members in order to ensure specimens are genuine. It is not wise to purchase meteorites on Ebay or other sources from those who are not IMCA members. This is a very tight-knit community made up of meteorite hunters, dealers, collectors, and scientists who look out for each other to make sure that the meteorites offered to the public are authentic and genuine. I encourage you to visit the IMCA website and get more information on what being a member means, and how your purchases from its members are guaranteed.

The Muonionalusta is a meteorite classified as fine octahedrite, type IVA (Of) which impacted in northern Scandinavia, west of the border between Sweden and Finland, about one million years BCE.
The first fragment of the Muonionalusta was found in 1906 near the village of Kitkiöjärvi.[1] Around forty pieces are known today, some being quite large. Other fragments have been found in a 25-by-15-kilometre (16 mi × 9.3 mi) area in the Pajala district of Norrbotten County, approximately 140 kilometres (87 mi) north of the Arctic Circle.
The meteorite was first described in 1910 by Professor A. G. Högbom, who named it "Muonionalusta", after a nearby place on the Muonio River. It was studied in 1948 by Professor Nils Göran David Malmqvist.[2] The Munionalusta, probably the oldest meteorite known to man, marks the first occurrence of stishovite in an iron meteorite.

Description
Studies have shown it to be the oldest discovered meteorite impacting the Earth during the Quaternary period, about one million years ago. It is quite clearly part of the iron core or mantle of a planetoid, which shattered into many pieces upon its fall on our planet.[3] Since landing here this meteorite has experienced four ice ages. It was unearthed from a glacial moraine in the northern tundra. A strongly weathered surface covered with cemented faceted pebbles leaves no doubt that its sojourn on Earth has been long and dramatic.
Composition
New analysis of this strongly shock-metamorphosed iron meteorite has shown a content of 8.4% nickel and trace amounts of rare elements—0.33 ppm gallium, 0.133 ppm germanium and 1.6 ppm iridium. It also contains the minerals chromite, daubréelite, schreibersite, akaganéite and inclusions of troilite.[2] For the first time, analysis has proved the presence of a form of quartz altered by extremely high pressure—stishovite,[2] probably a pseudomorphosis after tridymite. From the article "First discovery of stishovite in an iron meteorite":[1]
Stishovite, a high pressure polymorph of SiO2, is an exceptionally rare mineral...and has only been found in association with a few meteorite impact structures.... Clearly, the meteoritic stishovite cannot have formed by isostatic pressure prevailing in the core of the parent asteroid.... One can safely assume then that stishovite formation (in the Muonionalusta meteorite) is connected with an impact event. The glass component might have formed directly as a shock melt....
A 2010 study reported the lead isotope dating in the Muonionalusta meteorite and concluded the stishovite was from an impact event hundreds of millions of years ago: "The presence of stishovite signifies that this meteorite was heavily shocked, possibly during the 0.4 Ga [billion years] old breakup event indicated by cosmic ray exposure...."[4]
