Description

DESCRIPTION:

This is a superb fine Seymchan meteorite weighing about 418 grams and measuring about 67 mm long and 60 mm wide and 56 mm thick!. It is an outer corner piece which has been polished and acid-etched on the inner three sides so that you can enjoy not only the beautiful olivine gemstones, but also that beautiful Widmanstatten lines as well as the outer untouched raw surface. This palm-sized, heavy, meteorite is the largest and finest Seymchan in my collection! You will not find a nicer example, combining all these features in this size!

This Seymchan is an unusual meteorite in that it has parts that are classified a pallasite and other parts classified a type ungrouped coarse octahedrite (previously thought to be a IIE).   This example is offered at an incredibly low price for such a fine example! Seymchan is one of the nicest and sturdiest meteorites which does not rust! This means it does NOT require the special handling that some meteorites need and in particular some pallasites like Brahim and even Imilac!.

HISTORY AND IMPORTANCE OF THE SEYMCHAN METEORITE: This pallasitic and nickel-iron meteorite was discovered in a tributary of the Hekandue river, itself a tributary of Jasachnaja river in the Magadan district of the USSR in 1967, but this initial discovery was only a metal mass. Subsequent expeditions especially in 2004, discovered the mixed octahedrite and pallasite components, which made up only a minority of the total mass. Because it contains both pallasite components, and octahedrite components, this pallasite is now considered to have a mixed or anomalous classification by some authors. The metal portion was originally classified as a rare class IIE but is now considered a rare ungrouped iron, the pallasite portion belonging to the pallasite main group.  The olivine grains within the pallasites are considered semiprecious stones and greenish translucent examples are called peridot. Olivine dust is found in comet tails and around newly formed stars.

This is your chance to own an incredibly wonderful and important meteorite of immense beauty.
