“Even though Estonia is near the Baltic Sea in Northern Europe, researchers believe the arrowhead is more likely connected to this meteorite based on similar properties.”
The Baltic was already connected by trade routes to everywhere in Europe, and by extension, even to places far outside Europe, in very ancient times, because it was the primary world source of amber. I’m sure along with that trade, the Baltic people traded other valuable things, like meteor iron, as well.
In German, amber is "Bernstein."
Proto-Indo-European: *péh₂wr̥. (fire) and *steyh₂- (“to stiffen”)-- "fire stone."
