More Information:

In 1967, a geologist conducting a survey in a remote region of the Russian Far East stumbled upon a large iron mass in a dry riverbed. Later that year, a smaller mass of the same composition was found close by, with the aid of a land-mine detector. These finds together were named for the small, nearby settlement of Seymchan.

The first mass found was turned in to the Academy of Sciences of the USSR, and after its study was classified in 1974 as a Rare IIE Iron Meteorite. Further studies conducted on the Seymchan demonstrated it to be too different from other meteorites in this class and it was changed to an "Ungrouped Iron". It remained that way until 2004 when an additional 50kg of the meteorite was discovered.A portion of this, about 20%, actually contained the mineral Olivine, meaning it couldn't be simply an iron meteorite.

After further study it was again reclassified, this time as part of the main group of pallasite meteorites. Pallasite meteorites are the most beautiful and valuable meteorites. "Making up less than 2% of all meteorite falls", this type of meteorite is extremely rare. Pallasites are categorized as stoney-iron meteorites, as they are composed of olivine crystals embedded in a nickel-iron matrix.

Olivine, (meaning olive-green) due to its normal coloration, is in the same category as the gemstone, Peridot. So, Pallasite meteorites literally contain gemstones from other worlds. However, superheated liquid metal surrounding the Olivine crystals which is all contained in the rocky exterior of the meteorite can alter the color of the Olivine, giving it beautiful warm tones.

Pallasite meteorites are thought to be the remnants of the mantle cores of non-terrestrial bodies which after finding their way into our solar system are dragged into our atmosphere by the Earth's gravity. When these rare meteorites are thinly sliced then polished the true beauty of the Olivine crystals surrounded by its shiny smooth matrix is revealed. The first Pallasite meteorite was discovered in 1772 by the Siberian mountains of Krasnojarsk by Simon Peter Pallas, a German naturalist.
