Seymchan, Pallasite

The Seymchan meteorite was discovered in 1967: Buchwald described the recovery of the first specimens:

Seymchan is a heterogeneous pallasite; some specimens are nickel-iron, with inclusions typical of iron meteorites, and some specimens are mostly olivine.  Here’s a video from Youtube, of a Russian meteorite hunter excavating a large pallasitic specimen.

But most complete specimens have been cut.  The 1,548 gram complete pallasite individual pictured below has ties to the Fersman Mineralogical Museum in Moscow.
