Haben Sie schon einmal echten Sternenstaub gesehen?
Schwer vorstellbar?

Hier haben Sie die außergewöhnlich seltene Chance echten Sternenstaub des unendlichen Universums zu bekommen. Gebildet vor ca. 4,5 Millarden Jahren bei der Entstehung unseres Sonnensystems.
In den kleinen Fläschchen haben wir für Sie 4 Gramm (20ct) Sternenstaub, bzw. extraterestrische Edelstein-/Meteoritenkristalle abgepackt.

Sie kommen vom Pallasit "Jepara"

Ein Pallasit ist kosmischen Ursprungs, ein Meteorit also. Aber ein Meteorit, der Edelsteine aus dem unendlichen Welten-All auf die Erde bringt - Olivin oder auch Peridot* genannt. Diese funkelnden außerirdischen Edelsteine sind mit das seltenste, was wir auf der Erde finden.

Der Pallasit "JEPARA" fiel vor über 500 Millionen Jahren auf die Erde und wurde erst 2008 auf der Insel Java in Indonesien entdeckt. Durch einen großen Glücksfall ist es uns möglich diesen extrem seltenen Sternenstaub anzubieten!

KLICK>>> Exklusive Informationen im Fernsehbericht von Planetopia über den JEPARA Pallasit und seinen Peridot Kristallen. <<

Stellen Sie sich das mal vor! Was Sie da in Ihren Händen halten werden, ist ein Schatz unter den Schätzen!

Unendlich alt, unendlich selten und aus dem unendlichen Weltall...

 

*Peridot kommt auch auf der Erde vor

Name: Jepara
place: Java, Indonesia
coordinates: 6°36'S 110°44'E
classification: Pallasite, PMG
year: 2008
total weight: 499.5 kg
Meteorites are rarer than gold on the earth’s surface and only very few of them are Pallasites – a unique structure of metal and gemstone. They come from the asteroid belt between Mars and Jupiter and the material is 4.60 billion years old and part of the transition zone between the mantle and the core of an asteroid. The first one was discovered in 1749 at Krasnojarsk/Russia and described by Peter Simon Pallas, a German scientist. Consequently, the meteorite group was named Pallasites in honor of him. Over the last centuries only 36 pieces of the Main Group have been found, half of them are less than 20 kg. With reference to his weight Jepara is the fifth largest Main Group Pallasite.
History:
The meteorite was discovered in May 2008 during excavation activities at Jepara/Indonesia. A new hall for producing furniture had been under construction and Jepara has been dug out while building the foundation of this premises.
Physical characteristics:
The mass of the meteorite was 499.5 kg in an almost spherical shape with a shortest and longest diameter of 27.5 inch (70cm) and 33.5 inch (85cm). The crust of approximately 1 to 1.5 inch (2 - 4cm) is weathered and rusty.
Petrography:
Jepara shows a homogeneous distribution of coarse-grained rounded Peridots (Olivines) from approximately 6 -12 mm size (64 %). The groundmass is composed of secondary Magnetite (23 %), Nickel Sulfide and Sulfate (8%) and Schreibersite (5%). All the different elements are very finely spread, which gives Jepara a unique look, really different from other Pallasites. The Peridots are very clear and mostly without cracks.
Geochemistry:
Peridots are homogeneous in composition (FA12-13). Sulfides are composed of NiS and may represent a replacement product of Troilite, while Magnetite (Fe3O4) is a weathering product of primary FeNi phases. Schreibersite has the composition (Fe1.85Ni1.15).
This shows that Jepara has been on our planet for quite a long time before it was found.
Analyses:
The main analyses was done at University of Bayreuth/Germany and the isotope analyses are made by the University of Göttingen/Germany.
Preservation:
The slices are precisely cut by a diamond wire saw, then they are completely stabilized under vacuum with a special two components, very clear Epoxy Resin, which is used usually in labs. Later the slices are sanded and get their final surface with the same Resin. It makes the slices very firm and transparent. The reason for the preservation is not to protect the Meteorite from rust; there is no need, as all the metal is already gone. But after the NiFe has converted to Magnetite the structure is not stable enough to cut thin transparent slices.
