Found in Eastern Kenya, 2017
Sericho pallasite is an amazing discovery. Although recorded in 2016 and officially recognized as a meteorite in 2017, local lore has it that several large Sericho masses had been known to exist for generations.
Pure olivine (peridot) is naturally green, but Sericho’s sojourn on Earth has caused its crystals to terrestrialize and acquire yellow, orange, and brown hues. While pallasites are typically considered to be composed approximately 50% olivine and 50% nickel-iron, Sericho has a particularly high crystal density, with estimates putting it at 70–80% olivine.
