This is a Muonionalusta meteorite. The unique Widmanstätten pattern makes this one of the most beautiful meteorites. Showing this ring to new people really is amazing. Some people freak out completely when told this story and rightfully so.David Windestal

It’s freaking 20 million years older than the earth! Thanks to lead-lead dating we can with great accuracy determine that this meteorite is at least 4565.3 million years old. It’s just mind-bending. Even crazier is that the universe is 3 times older than that!//Watch the video from David Windestal for more info:
The Muonionalusta is a meteorite classified as fine octahedrite, type IVA (Of) which impacted in northern Scandinavia, west of the border between Sweden and Finland, about one million years BCE.
Studies have shown it to be the oldest discovered meteorite impacting the Earth during the Quaternary Period, about one million years ago. It is quite clearly part of the iron core or mantle of a planetoid, which shattered into many pieces upon its fall on our planet./wikipedia
