A triangle of Seymchan meteorite on a sterling silver chain.

Seymchan was found in 1967 in the dry bed of the Hekandue River, in the Magadan district of Russia. It is a pallasite, and only about 380kg has ever been recovered. Cut and etched, it shows the Widmanstätten pattern, a lattice that only forms when molten iron cools over millions of years, which is why it cannot be made on Earth.

Seymchan resists rust better than most iron meteorites, so it is the most forgiving of the three we work with. Every piece is cut differently, so yours will not look exactly like the photograph.
