In the 1960s, two large metallic masses were found in a streambed in an infamous part of Siberia where Stalin's gulags are located. Identified as meteorites, they were named Seymchan after a nearby town. Some specimens of Seymchan contain olivine crystals scattered throughout the matrix, others have no such crystals at all and then there are the "transitional" specimens which feature bands of crystals—and the complete slice now offered is a superlative example of the latter variety. A prominent display of this meteorite's array of its nickel-iron alloys referred to as a Widmanstätten pattern is also in evidence. This metallic latticework is indicative of a slow cooling rate that provided sufficient time — millions of years — for its two metallic alloys to form their crystalline habit and as such it's diagnostic in the identification of a meteorite. This meteorite also contains crystals of peridot, the birthstone of August. From the Macovich Collection, the world's most renowned collection of aesthetic iron meteorites.

此件隕石於60年代在西伯利亞被發現,隕石上有兩種金屬的結晶體,體現了天體在經歷了數百萬年的時間沈積。基中一種為橄欖石晶體,是八月的誕生石。來自於Macovich收藏,其為世界上最著名的隕石收藏鑑賞家。
