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. 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!
This ring is one of my most prized possessions now.
A big thanks to "Inspire to make" who made the video that inspired me to make this ring
