Meteorite specimens are identifiable by undulating serrations notable on the silhouette of the fragment. Called regmaglypts, in reference to the thumbprint sized indentations on the body of specimens, these reliefs are formed by ablation when the original meteor burned through the Earth’s atmosphere. As iron-ore rich meteorites, these specimens are often dark silver and grey with deep tones and display a brusque finish. Some meteorite specimens feature sharp-edges of torn metal showing evidence of violent separation during atmospheric explosions or upon high speed impact on the frozen ground. Oftentimes smaller fragments or shrapnel extracted from the larger meteor during impact may be found nearby the meteor crash site. We sustainably source rigmalypted meteorite specimens from the Sikhote-Alin mountains in Russia. Measurements of the potassium and argon content of Sikhote-Alin iron meteorites, by activation analysis, allowed scientists to date the age of the solidification of the meteorites to circa 4.6 billion years ago.
