Seymchan 					Location 62  54'N, 152  26'E
Magadanskaya distrikt, Russia  
Find: June 1967
Pallasite
Circumstances of the fall or discovery: The larger specimen has been found by the geologist F. A. Mednikov during a geological survey. 
The meteorite hardly seen was lying among the stones of the brook-ebd. 
The smaller specimen was found at a distance of 20 m from the first one by I. H. Markov with a mine detector in october 1967. 
The main mass was turned to the Academy of Sciences of the USSR.
A small section of iron was analyzed by J.Wasson and it was determinated to be a member of chemical group IIE.
During a 2004 expedition additional masses were found. Many of them were found to contain silicates with a pallasitic texture.
So it was reclassificated to main group pallasite. And now Seymchan is an anomalous pallasite due to its high Ir content (van Niekerk et al. 2007)

Classification: Pallasite (Main group). 

Transparent olivine is the most beautiful mineral in meteorites without any doubt. Olivines from Seymchan meteorite are VERY GOOD.
We found a piece that was almost without metal - the olivines were just separated. Among a lot of crystals we found some that were without cracks,
so it was possible to make some gems. see page for gems
