Seymchan is a meteorite called 'Pallasite'; discovered in the dried bed of the Hekandue River, in the Magadan district (Russia), near the colony of Seymchan, in 1967.

The main mass of 272.3 kg was discovered during a study conducted in June 1967 by geologist FA Mednikov. The mass was triangular in shape, lying among the stones of the streambed.
A second specimen weighing 51 kg was found with a mine detector 20 meters from the first one in October by Markov.
The main mass was preserved at the USSR Academy of Sciences.

During a new expedition in 2004, Dmitri Kachalin recovered approximately 50 kg of new material. Remarkably, about 20% of the new specimens contained olivine crystals. The pallasitic structure had not yet been discovered during studies on small sections of the original mass, which consisted solely of metal.

Seymchan belongs to the main group of pallasites, but it is considered abnormal due to its high iridium content. Before the discovery of its pallasitic structure, it was classified as an anomalous coarse octahedrite IIE.

This perfect slice of Seymchan is considered to be stable, resistant to rust.

Beautiful specimen of quality to keep in your collection!!!
